+
+# The OUTPUT_LANGUAGE tag is used to specify the language in which all
+# documentation generated by doxygen is written. Doxygen will use this

+# The default language is English, other supported languages are:
+# Brazilian, Catalan, Chinese, Chinese-Traditional, Croatian, Czech, Danish,
+# Dutch, Finnish, French, German, Greek, Hungarian, Italian, Japanese,

+Features
+========
+
+configurable audio streaming software
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ para_server streams binary audio data (mp3/ogg files) over
+ local or remote networks. It contains two built-in streamers:
+ the http streamer and the ortp streamer.
+
+ para_audiod runs on the client side and connects to
+ para_server. The audio stream is read back and sent through
+ any of paraslash's filters (mp3 decoder, ogg vorbis decoder,
+ volume normalizer,...) and the resulting stream is written to
+ an external program's standard in, usually an audio player,
+ like para_play that uses alsa. It is possible to grab the
+ stream at any position in the filter chain.
+
+ The receiving/filtering software is also available as
+ standalone command line tool: para_recv grabs the http or ortp
+ stream and writes to stdout; para_filter reads from stdin,
+ converts the stream according to the given --filter command
+ line options and writes the transformed stream to stdout.
+
+mysql-based audio file selector:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ the (optional) mysql database tool manages some statistics on
+ your audio files. It contacts the mysql server to decide which
+ song to play next by sending a user-defined sql-query. This
+ allows rather sophisticated configurations and is explained
+ in detail in README.mysql.
+
+small memory footprint:
+~~~~~~~~~~~~~~~~~~~~~~~
+ paraslash is lightweight. The stripped binary of para_server
+ with all its features compiled in (mysql/dopey dbtool,
+ mp3/ogg support, http/ortp support) is about 100K on i386
+ under Linux. para_audiod is even smaller.
+
+command line interface, including shell:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ para_client without arguments starts interactive (shell)
+ mode. Otherwise, command is sent to para_server directly
+ and output is dumped to stdout. This can be used by any
+ scripting language to produce user interfaces with very little
+ programming effort.
+
+authentication/encryption via openssl:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ All connections between para_server and para_client are
+ encrypted by default. For each user of paraslash you must
+ create a public/secret key pair for authentication/encryption.
+
+various user interfaces and utilities:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ o para_gui. Curses based interface, displays information in a
+ curses window and can be used to easily control para_server
+ and para_audiod.
+
+ o para_sdl_gui. Shows pictures (on a per song basis) and
+ other information about the current audio file. Can be used
+ as a screen saver.
+
+ o para_krell. A gkrellm2 plugin that shows small pics and is
+ able to launch 27 different commands by clicking on the image.
+
+ o para_slider. User-friendly stream creator for people who
+ don't like their keyboard.
+
+ o para_dbadm. Simple curses interface for changing attributes.
+
+ o para_fade. Simple volume fader and alarm clock.

+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+\f
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+\f
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+\f
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+\f
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN

+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) 19yy <name of author>

+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of

+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) 19yy name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program

+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+Paraslash install notes
+=======================
+
+Any knowledge of how to work with mouse and icons is not required.
+
+Install all needed packages
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+See README for a list of required software. Don't be afraid of the long
+list of unusal libraries: Most of them are only needed for optional
+programs. Autoconf will detect what is installed on your system and
+will only build those executables that can be built with your setup.
+
+
+Install server and client
+~~~~~~~~~~~~~~~~~~~~~~~~~
+Install the package on all machines, you'd like this software to run on:
+
+ (./configure && make) > /dev/null
+
+There should be no errors (but probably many warnings about missing
+software). Then, as root,
+
+ make install
+
+
+Setup user list and create rsa keys
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+If you already have your rsa keys, skip this step. If you are new
+to paraslash, you have to generate an rsa key pair for each user you
+want to allow to connect. You need at least one user.
+
+Let's assume that you'd like to run the server on host server_host
+as user foo, and that you want to connect from client_host as user bar.
+
+As foo@server_host, create ~/.paraslash/server.users:
+
+ target=~/.paraslash/server.users
+ key=~/.paraslash/key.pub.bar
+ perms=DB_READ,DB_WRITE,AFS_READ,AFS_WRITE
+ mkdir -p ~/.paraslash
+ echo "user bar $key $perms" >> $target
+
+This gives bar full privileges.
+
+Change to the bar account on client_host and generate the key-pair
+with the commands
+
+ key=~/.paraslash/key.bar
+ mkdir -p ~/.paraslash
+ (umask 077 && openssl genrsa -out $key)
+
+Next, extract its public part:
+
+ pubkey=~/.paraslash/key.pub.bar
+ openssl rsa -in $key -pubout -out $pubkey
+
+and copy the public key just created to server_host:
+
+ scp $pubkey foo@server_host:.paraslash/
+
+Finally, tell para_client to connect to server_host:
+
+ echo 'hostname server_host' > ~/.paraslash/client.conf
+
+Start para_server
+~~~~~~~~~~~~~~~~~
+ para_server
+
+Now you can use para_client to connect to the server and issue
+commands. Open a new shell (as "bar" on "client_host" in the above
+example) and try
+
+ para_client help
+ para_client si
+
+to retrieve the list of available commands and some server info.
+
+
+Choose your database tool (dbtool)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+You have three options:
+
+ 1. Use the mysql dbtool which comes with paraslash and requires
+ mysql. This is recommended.
+
+ 2. Use your own database tool. If you have that already,
+ skip this step.
+
+ 3. If you can not use the mysql dbtool and you just want
+ to quickly make paraslash working, use the dopey dbtool.
+ The directory which is searched for audio files can be given
+ via the server option --dopey_dir.
+
+ Note, however, that dopey is _really_ dopey. It scans
+ $dopey_dir on every audio file change and chooses one
+ randomly. You get the idea. Have a look at its source code
+ and feel free to modify.
+
+
+The current database tool can be changed at runtime via
+
+ para_client cdt new_dbtool
+
+If you have choosen 1. above, read README.mysql and follow the
+instructions given there. Return to this document when ready.
+
+
+Start streaming manually
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+ para_client play
+ para_client stat 2
+
+This starts streaming and dumps some information on the current song
+to stdout.
+
+You should now be able to listen to the stream with any player
+capable of reading from stdin. To check this, try the following
+on client_host:
+
+ mp3:
+
+ para_recv -r http:-i:server_host | para_filter -f mp3 -f wav | para_play
+ or
+ mpg123 http://server_host:8000/
+ or
+ xmms http://server_host:8000/
+
+ ogg:
+
+ para_recv -r http:-i:server_host | para_filter -f ogg -f wav | para_play
+
+If this works, proceede. Otherwise doublecheck what is logged by
+para_server and use the --loglevel option of para_recv to increase
+verbosity.
+
+Configure para_audiod
+~~~~~~~~~~~~~~~~~~~~~
+In order to automatically start the right decoder at the right time
+and to offer to the clients some information on the current audio
+stream and on paraslash's internal state, you should run the local
+audio daemon, para_audiod, on every machine that is supposed to play
+the audio stream. Try
+
+ para_audiod -h
+
+for help. Usually you have to specify at least server_host as the
+receiver specifier, like this:
+
+ -r http:-i:server_host
+
+The prefered way to use para_audiod is to run it once at system start
+as an unprivileged user. para_audiod needs to create a "well-known"
+socket for the clients to connect to. If you want to change the
+default socket (e.g. because you do not have write access for the
+directory where the socket resides), use the -s option or the config
+file to change the default. Note that in this case you'll also have
+to specify the same value for para_audioc's -s option.
+
+If para_server is playing, you should be able to listen to the audio
+stream as soon as para_audiod is started. Once it is running, try
+
+ para_audioc stat
+
+That should dump some information to stdout. Other commands include
+
+ para_audioc off
+ para_audioc on
+ para_audioc sb
+ para_audioc term
+ para_audioc cycle
+
+
+Start para_gui
+~~~~~~~~~~~~~~
+para_gui reads the output of "para_audioc stat" and displays that
+information in a curses window. It also allows you to bind keys to
+arbitrary commands. There are several flavours of key-bindings:
+
+ o internal: These are the built-in commands that can not be
+ changed (help, quit, loglevel, version...).
+
+ o external: Shutdown curses before launching the given command.
+ Useful for starting other ncurses programs from within
+ para_gui, e.g. aumix or para_dbadm. Or, use
+
+ para_client mbox
+
+ to write a mailbox containing one mail for each file
+ in the mysql database and start mutt from within para_gui
+ to browse your collection!
+
+ o display: Launch the command and display its stdout in
+ para_gui's bottom window.
+
+ o para: Like display, but start "para_client <specified
+ command>" instead of "<specified command>".
+
+
+That's all, congratulations. Check out all the other optional gimmics!
+
+Troubles?
+~~~~~~~~~
+If something went wrong, look at the output. If that does not give
+you a clue, use loglevel one (option -l 1 for most commands) to show
+debugging info. Almost all paraslash executables have a brief online
+help which is displayed by using the -h switch.
+
+Still not working? Mail the author Andre Noll <maan@systemlinux.org>
+(english, german, or spanish language). Please provide enough info
+such as the version of paraslash you are using and relevant parts of
+the logs.

+NEWS
+====
+
+0.?.? (to be announced) "atomic duality"
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ o update to gengetopt-2.16
+
+0.2.10 (2006-02-17) "cyclic attractor"
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Huge documentation update, a scrollable window for para_gui, ortp
+improvements, and of course many small fixes not mentioned here.
+The diffstat below is rather misleading as most insertions are due
+to the new source documentation.
+
+ o autoconf cleanup
+
+ o para_server also uses the new error subsystem
+
+ o lots of new documentation (UTSL)
+
+ o gui improvements:
+ - keysyms for cursor keys and for next/previous page keys
+ - scrollable output window
+ - new internal commands: scroll up/down, page up/down
+ - fix color of command output.
+
+ o ortp: the --chunk_time and --header flags are no longer needed
+ for para_recv/para_audiod as this information is now encoded in
+ each rtp packet sent by para_server.
+
+New files: daemon.h net.h ringbuffer.c ringbuffer.h string.h web/para.css

+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Internal audiod receivers/filters, the new error subsystem and
+a lot of small improvements.
+
+ o para_recv and para_filter are integrated into the para_audiod
+ binary, i.e. audiod no longer spawns a new process for
+ each receiver/filter. As para_recv and para_filter might be
+ useful as standalone programs, they still get built (linked
+ against the same object files that are also used for audiod).
+
+ o further ortp timing improvements should reduce the CPU usage
+ of the ortp receiver.
+
+ o improved audio grabbing. The 'grab' command of para_audiod
+ has its own set of command line options. Read the output of
+ "para_audioc help grab" for more info.
+
+ o oggdec: configurable input prebuffer size.
+
+ o the new error subsystem gives better error diagnostics
+ and reduces code size.

+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The new modular filter design and the para_play-hangs bugfix.
+
+ o new executable: para_filter. It combines para_mp3dec,
+ para_oggdec and para_compress. It also adds a further filter
+ type, wav, that just inserts a wave header at the desired point
+ of the filter chain. All 'piping' is done in-memory (i.e. no
+ read/write operations are used).
+
+ o para_play: fix a stupid bug that caused it to hang under

+0.2.7 (2006-12-27) "transparent invariance"
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Not many user-visible changes but a fair amount of internal improvements.
+
+
+ o The http sender buffers data if it can not be sent
+ out immediately (because the socket is not writable). This
+ should prevent para_server from shutting down the connection
+ too early on a loaded network.
+
+ o para_play also prebuffers data if it is told to start at a
+ future time by the --start_time option.
+
+ o The return of para_recv: It combines para_ortp_recv and
+ para_http_recv. Use the --receiver option to switch between
+ the two. para_recv builds without libortp, but contains
+ only the http receiver in this case.
+
+ o update to ortp 0.8.1. As this ortp release contains incompatible
+ changes, para_recv-0.2.7 won't link against older ortp libs.
+
+ o improved ortp timings.
+
+ o use of gcc-extensions that #define away for non-gcc and
+ gcc < 3.0.

+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Transparent session encryption (uses openssl's Alleged RC4 cipher),
+the internal find command and several other improvements and cleanups.
+
+ o Encrypt the session if encryption is requested by the client
+ (default for para_client 0.2.6). This is backwards
+ compatible, so older clients can still connect to para_server
+ 0.2.6. Use the new client option --plain to request an
+ uncrypted session (off by default, must be set to on in
+ order to connect to para_server 0.2.x with 0 <= x <= 5).
+
+ o para_server uses an internal function to locate audio files
+ rather than calling find(1). The server option
+ --mysql_audio_file_dir replaces --mysql_find_cmd.
+
+ o documentation update
+
+ o man pages
+
+ o header file cleanup
+
+ o para_client code cleanup
+
+ o para_gui: faster display of output of display commands

+0.2.5 (2005-10-13) "aggressive_resolution"
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+This release adds internal senders, i.e. no more external programs are
+spawned for sending out the audio data. There are two different senders
+available: The http sender and the ortp sender (former para_send which
+is no longer needed).
+
+The new sender code has a plugin-like design so it can be easily
+extended should there be be any future need for supporting another
+network streaming protocol. All senders are completely independent of
+each other. In particular, the http and the ortp sender can operate
+in parallel.
+
+ o new server command: sender to control senders at runtime.
+ Read the output of "para_server -h" and "para_client help
+ sender" for more information.
+
+ o para_recv renamed to para_ortp_recv
+
+ o new executable: para_http_recv, a simple command line
+ http receiver.
+
+ o major afs/mp3/ogg code simplifications due to internal
+ senders.
+
+ o ogg timing improvements
+
+ o fix several minor memory leaks (found by valgrind)
+
+ o empty stream definitions work again
+
+ o com_ne(): ignore errors on remove
+
+ o audiod: fix segfault on server restart
+
+New files: http.h http_recv.c http_recv.ggo http_send.c ortp.h ortp_recv.c

+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Several small improvements, fixes and the new grab command.

+ o audiod:
+ - new command: "grab" to grab the output of the stream reader
+ or any filters. Read the output of "para_audioc help grab"
+ for more information.
+ - fix memory leak
+ - code cleanup
+
+ o audioc: new command line option: --bufsize to specify a
+ buffer size different from the default size 8192.
+
+ o improved error diagnostics for para_play.
+
+ o new configure option: --enable-ssldir so search for openssl in
+ non-standard places
+
+ o sdl_gui: Make it look nice again for 1024x768
+
+ o server: report total size of memory allocated with sbrk by malloc,
+ new command line option: --announce_time

+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Two new executables and major feature enhancements.
+
+ o audiod filters: It is now possible to specify arbitrary many
+ (including none) filters for each supported audio
+ format. This can be used e.g. for normalizing volume,
+ transforming or grabbing the audio stream, or for using
+ visualizers. Read the output of "para_audiod -h" for the
+ syntax of the new --filter_cmd option.
+
+ o new executable: para_play, a tiny alsa player. It
+ can play wave files or raw pcm (16 bit little endian)
+ from stdin.
+
+ o new executable: para_compress, a dynamic range compressor
+ intended to keep audio output at a consistent volume. Derived
+ from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
+
+ o audiod: New option: --stream_delay. This can be used in
+ a local network to syncronize the audio output of all
+ clients that play the same stream.

+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Mostly internal changes in this release, but also some new commands
+for the mysql database tool.
+
+ o cleanup exec.c, fix para_exec bug
+ o compile time loglevel (log messages below the given level
+ won't be compiled in, which reduces the size of the
+ resulting binaries)
+ o new log macros that shorten the size of the source code.
+ o workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
+ to send only zeros. With this workaround, para_audioc works
+ again.
+ o avoid gcc-4 warning: conflicting types for built-in function 'clog'
+ o new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
+ (new entry), "snp" (set numplayed). Read the manual for more
+ information.

+0.2.1 (2005-08-15) "surreal experience"
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Here comes paraslash-0.2.1. It contains a couple of new features and,
+surprise, only minor bug fixes.
+
+ o kill noisy mp3 debug message
+ o cleanup of the build system
+ o para_server and para_client directly use the crypto routines
+ of the openssl library rather than invoking the openssl command
+ line utitlity
+ o server/audiod: new option --user to switch to the given user
+ when invoked as root. Read the output of "para_server -h" for
+ more information.
+ o gui/sdl_gui: new option --stat_cmd to be used to retrieve the
+ status. Default: "para_audioc stat"
+ o sdl_gui: new option --pic_cmd to be used to download the picture.
+ Default: "para_client pic"
+ o audiod: 5 slots ought to be enough for everybody
+ o audiod: new status item: Uptime, kill hup command

+0.2.0 (2005-08-06) "distributed diffusion"
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+After several month of increased development activity, paraslash-0.2.0
+has arrived. It contains many new features and is much more
+self-contained than the old 0.1.x series. Enjoy!
+
+
+ o para_server: fix hang on song change and crash on sighup.
+ Speed up mysql queries. The DIR_LIKE macro is gone.
+ o new executables: para_audiod, the local audio daemon that
+ starts playback (uses SCM_CREDENTIALS socket magic) and
+ para_audioc, the corresponding client.
+ o new executables: para_mp3dec/para_oggdec, two really teensy
+ decoders. para_mp3dec is based on libmad, para_oggdec requires
+ libvorbisfile.
+ o ovsend/ovrecv are capable of streaming ogg as well as mp3, so
+ they are now called para_send and para_recv respectively.
+ o documentation updates
+ o para_gui is themable. For now there is the default theme that
+ looks as before and the simple theme: blue and easy.
+ o gui: audio streaming is now handled by audiod. Time display shows
+ playback time rather than streaming time
+ o slider: update to libzmw-0.2.0
+ o para_krell: fix crash on server shutdown
+ o switch from gzip to bzip2

+0.1.7 (2005-04-18) "melting penetration"
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The main change in this release is clearly the oggvorbis rewrite,
+but there are also lots of smaller changes. If you intend to use both
+the mp3 and the ogg plugin, it is recommended to use software mixing,
+e.g. the dmix plugin which is provided by ALSA.
+
+ o new executables: para_ovsend and para_ovrecv for sending/receiving
+ oggvorbis files via rtp. Requires the open rtp library. Get it at
+ http://www.linphone.org/ortp/
+ o rewrite of the ogg_vorbis core code
+ o configure detects libzmw and, if detected, includes
+ para_slider to the list of binaries to be built by make
+ o server stream writers read from their associated fifo rather
+ than from stdin
+ o slider: two new sliders, lastplayed and numplayed
+ o fix nasty double free bug which caused random segfaults in case of
+ mp3 files with invalid header information
+ o gui: new command line option: --stream_timeout=seconds to
+ deactivate a slot if it is idle for that many seconds (default=`5')
+ o diffstats

+0.1.6 (2005-03-05) "asymptotic balance"
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Only little user-visible changes in this release. Mainly bugfixes and
+core code cleanup. This is probably the most stable version ever if you
+stick to mp3...
+
+ o fix several memory leaks
+ o rename default name of mysql database from "music" to "paraslash".
+ Use para_server's --mysql_database option if you do not want to
+ rename your old database.
+ o rework ogg vorbis code
+ o make update command work on mysql servers with LOCAL_INFILE
+ disabled
+ o gui: improved stream I/O (slots)
+ o simplified audio format API
+ o para_pob_ogg is gone
+
+0.1.5 (2004-12-31) "opaque eternity"
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Let's slide gently into the new year.
+
+ o new: para_slider (not built automatically, type "make
+ para_slider" to build). A toy for those who always felt that
+ creating stream definitions is difficult. See screenshots,
+ README and FEATURES for more info.
+ o improved signal handling. Fixes server segfault on SIGHUP
+ for linux kernels newer than Aug 24 2004 and makes para_gui
+ race-free.
+ o reload database tool on SIGHUP
+ o improved help message for sl
+ o do not log "broken pipe" messages as errors. They are
+ perfectly ok.
+ o fix wrong error message on permission errors
+
+0.1.4 (2004-12-19) "tunneling transition"
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
+Hopefully, most of them got wiped out with this release. Some
+enhancements went also in.
+
+ o improved error diagnostics for all commands
+ o stradd/picadd: overwrite previous contents if entry already
+ exists, rather than returning errors
+ o stradd: use current stream if invoked without args
+ o faster (and hopefully more stable) ogg-vorbis handling
+ o para_krell: reap children to avoid zombie-flooding in case
+ no server is running
+ o si: report also server pid
+ o server: don't busy-loop if dbtool reports only invalid files.
+ o gui: CTRL+C works again, fix stream_read command line option
+ o fix pic_add, hist
+ o fix mysql dbtool startup in case no database exists
+ o many small fixes and cleanups
+
+0.1.3: (2004-12-10) "vanishing inertia"
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Starting from this release, the database tools are integrated in the
+server binary. This decreases server startup time, reduces code size
+and speeds up database commands. However, the layout of the underlying
+mysql database changed only slightly and 0.1.3 should be backwards
+compatible in that respect.
+
+Visible changes:
+
+ o If mysql is not detected at compile time, or fails to init
+ at runtime, fall back to the dopey database tool which should
+ always work.
+ o para_dbtool and dbtool.conf are gone. All mysql specific
+ options are read from server.conf and are prefixed by 'mysql_'.
+ o new command: cdt (change database tool)
+ o new command line option: dbtool (choose startup database tool)
+ o The name of current stream is now stored in the database,
+ so paraslash remembers its current stream when restarted.
+ o new command: csp (change stream and play)
+ o para_gui also reports current database tool and server uptime
+
+
+0.1.2: (2004-11-28) "spherical fluctuation"
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Point release before the big dbtool changes go in.
+
+ o dbtool: rename ca to cam (copy all meta data). It now also
+ copies numplayed and lastplayed time as well as the picture
+ id.
+ o fix endless-loop-bug caused by mp3 files with invalid header
+
+0.1.1: (2004-11-05) "floating atmosphere"
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ o gkrellm plugin
+ o new dbtool command: mbox. Browse your sound-file collection
+ with your favorite mail reader.
+ o several small fixes
+
+0.1.0: (2204-10-22) "rotating cortex"
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ o fix logging bug for loglevel > VERBOSE
+ o fix skip command
+ o correct timings for vbr mp3s
+ o modular audio format support
+ o ogg-vorbis support (experimental)
+ o new server option: autoplay
+
+0.0.99: (2004-07-25) "harmonic deviation"
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ o rename projectname from icc to paraslash (play, archive, rate
+ and stream large audio sets happily)
+ o paraslash is no longer restricted to one particular audio
+ streaming software
+ o new dbtool commands (stradd, strq, strdel) for easy stream
+ managment w/o configuration file. That obsoletes stream_defs
+ file/config option for dbtool.
+ o picadd accepts jpeg data from stdin
+ o new server commands: ps (select previous stream), sc (song change)
+ o new default pictures for sdl_gui
+ o gui: new key_map option for binding commands and internal
+ functions to arbitrary keys, nice help screen, rip out
+ soundcard/linux specific stuff, avoid noise artefacts while jumping,
+ show silly logo on startup
+ o new executables: para_fade for fading volume, para_dbadm for
+ manipulating attributes
+ o cdb adds _all_ tables to mysql database
+ o revised and beautified documentation
+ o sample dbtool rewritten in C
+ o autoconf
+
+0.0.98: (2003-12-26) "incremental smoothness"
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ o kick icecast in favour of poc. That removes some races and reduces
+ core code considerably.
+ o cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
+ give finer info on afs' status.
+ o gui can start decoder (see config options). Further new gui
+ commands: refresh (^L), jmp (F1-F10)
+ o gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
+ terminates gui. This fixes dead instances consuming memory
+ continuously.
+ o new dbtool command: verb for sending verbatim sql queries.
+ o fix pid_list races (by removing pid_list)
+ o codename funnies
+
+0.0.97: (2003-10-26)
+~~~~~~~~~~~~~~~~~~~~
+ o installation prefix now defaults to /usr/local
+ o new commands for gui: snozze, sleep and reread config
+ o config file for gui and sdl_gui
+ o fix problems with filenames containing funny characters
+ (reported by Thomas Forell)
+ o improved signal handling for gui, now it rereads conf on SIGHUP
+ o new dbtool command: cdb (create database)
+ o switch from argtable to gengetopt
+ o major code cleanup and speed improvements
+ o fix several potential buffer overflows
+ o many small fixes and cleanups
+
+0.0.96 (2003-08-30)
+~~~~~~~~~~~~~~~~~~~
+ o easy stream_defs syntax
+ o sdl_gui can display images associated to the file being played
+ o Major feature enhancements for icc_gui including dynamic text
+ placement and the top/bottom window design
+ o vrfy/clean now also checks for NULL values in attributes as
+ well as for invalid picture pointers
+ o fix long outstanding case sensitivity bug
+ o many small fixes and cleanups
+
+0.0.95 (2003-06-29)
+~~~~~~~~~~~~~~~~~~~
+ o sdl gui runs much faster
+ o new dbtool command: ca (copy attributes)
+ o count and display number of times the song has been played
+ o new feature: scoring
+ o command line options for sdl_gui
+ o simpler syntax of streams file
+ o decrease network traffic of stat
+ o fix zombie bug
+ o many small fixes and cleanups
+
+0.0.94 (2003-05-04)
+~~~~~~~~~~~~~~~~~~~
+ o new server command: ns (next stream)
+ o new icc_gui command: c (change stream)
+ o internal mp3info
+ o stat shows also id3 tag info
+ o new sdl based gui
+ o log flodding bug fixed
+ o many small fixes and cleanups
+
+0.0.93 (2003-03-28)
+~~~~~~~~~~~~~~~~~~~
+ o colors for icc_gui
+ o icc_gui sets volume directly (linux only)
+ o proper locking that fixes some races
+ o fix security bug that caused commands to be executed even
+ with unsufficient permissions
+ o new command: hup to make all servers reread their configuration file
+ o icecast meta data streaming
+ o many small fixes and cleanups

+Paraslash README
+================
+Paraslash is an acronym for
+
+ Play, archive, rate and stream large audio sets happily
+
+It contains the following programs:
+
+- para_server (obligatory):
+
+ This server listens on a specified tcp port and accepts the
+ usual commands such as play, stop, pause, next. However, there
+ are many more commands.
+
+ For audio streaming, at least one sender must be activated.
+ At the moment, paraslash contains two internal senders:
+
+ The http sender is recommended for public streams that can
+ be played by any player like mpg123, xmms, winamp...
+
+ The ortp sender is recommended for LAN streaming and for
+ private streams that require authentication.
+
+ It is possible to activate more than one sender simultaneously.
+ All senders have the same set of commands that allow to
+ control the access permissions of the stream.
+
+ para_server needs a database tool to work, mainly to determine
+ which song to stream next. There are two database tools
+ available: mysql and dopey. The former is recommended as dopey
+ is only meant as a fallback and as a starting point for people
+ that want to write their own database tool for paraslash.
+
+ The mysql database tool connects to a mysql server which
+ holds information on your audio files. It has several unusual
+ features, see README.mysql for details.
+
+- para_client (obligatory):
+
+ The client program to connect to para_server.
+
+- para_recv (optional)
+
+ A command line http/ortp stream grabber.
+
+- para_filter (optional)
+
+ An filter program that converts from stdin and writes to
+ stdout. This one is independent from the rest of paraslash,
+ so it might be useful also for different purposes.
+
+ para_filter combines an mp3 decoder an oggvorbis decoder
+ and a volume normalzer. New filters can be added easily due
+ to the modular design. If more than one filter is specified,
+ the given filters are 'piped' together in-memory, i.e. without
+ calling any of the read(2)/write(2)/select(2) etc. functions.
+
+- para_play (optional)
+
+ A small wav/raw player for alsa.
+
+- para_audiod (optional, but recommended):
+
+ The local daemon that starts playback and collects information
+ from para_server to be forwarded to local clients.
+
+ para_audiod reads the audio stream from the network if
+ para_server indicates that there is a stream available. It may
+ be sent through any of the supported filters (see para_filter
+ above) before the result is fed to the output software
+ (default: para_play) which must be capable of reading from
+ stdin, but is not restricted otherwise.
+
+- para_audioc (optional, but recommended)
+
+ A small client that can talk to para_audiod. Used to control
+ para_audiod and to receive status info. It can also be used to
+ grab the stream at any point in the filter chain. para_audioc
+ is needed by para_gui, para_sdl_gui and para_krell, see below.
+
+- para_gui (optional, but recommended):
+
+ Themable ncurses-based gui. It calls para_audioc and presents
+ the obtained information in an ncurses window. para_gui
+ provides key-bindings for the most common commands and new
+ key-bindings can be added easily.
+
+- para_sdl_gui (optional):
+
+ SDL-based gui. Similar to para_gui but presents its output in
+ an X window (fullscreen mode is also available) and can display
+ jpg images on a per song basis. para_sdl_gui provides an input
+ prompt to enter arbitrary commands. However, it can also be used
+ non-interactively (e.g. as a screen saver) via the -i switch.
+
+- para_krell (optional, only useful in conjunction with the mysql dbtool):
+
+ A plugin for gkrellm which shows small pictures of the
+ current song. It allows you to launch 27 different commands
+ by clicking in different areas of its picture (9 small squares
+ x 3 mouse buttons).
+
+- para_fade (optional):
+
+ A (Linux-only) alarm clock and volume-fader.
+
+- para_dbadm (optional, only useful in conjunction with the mysql dbtool):
+
+ Very simple curses-based frontend which uses libmenu. Useful
+ for quickly changing the attributes of the current song
+ (e.g. from para_gui as an external command).
+
+- para_slider (optional, only useful in conjunction with the mysql dbtool):
+
+ A small X application which shows a scrollbar for each
+ attribute defined in the mysql database. It creates a stream
+ definition from the values of the scrollbars. This allows
+ to smoothly change the mood of the given stream without any
+ file editing.
+
+- bash_completion (optional):
+
+ A small bash script for inclusion in ~/.bashrc. It gives you
+ command line completion for some paraslash commands.
+
+REQUIREMENTS:
+~~~~~~~~~~~~~
+In any case you need
+
+ - gcc, the gnu compiler collection (shipped with distro): gcc-3
+ or newer is prefered, but gcc-2.95 is still supported. Note
+ that gcc-2.95 may spit out many warnings like unused function
+ parameters and missing initializers. These are all harmless
+ and may be ignored.
+
+ - openssl (needed by server, client): usually shipped with
+ distro, but you might have to install the "development"
+ package as well
+
+ http://www.openssl.org/
+
+ - software mixing, e.g. ALSA and the direct mixing plugin (dmix)
+
+If you want to use the mysql-based dbtool (recommended), you also need
+
+ - mysql-server
+ - mysql-client
+ - libmysqlclient
+
+These are usually shipped with the distro but probably not installed
+by default.
+
+The mp3 decoder of para_filter is based on libmad:
+
+ http://www.underbit.com/products/mad/
+
+If you prefer to use the libmad package provided by your distributor,
+make sure to install the corresponding development package as well.
+
+If you want to stream ogg vorbis files you'll need:
+
+ - libogg, libvorbis, libvorbisfile, and a command line ogg vorbis
+ player, e.g. para_filter or ogg123.
+
+ http://www.xiph.org/downloads/
+
+Note that para_audiod still works even if neither mp3 nor ogg support
+was compiled in. You'll have to use the --no_default_filters option
+in this case (and e.g. "mpg123 -" as the stream write command).
+
+If you intend to use the optional ortp streamer:
+
+ - libortp
+
+ http://www.linphone.org/ortp/
+
+
+For the optional SDL-based gui, the following packages must be installed:
+
+ - X (usually shipped with distro)
+
+ http://www.x.org/
+
+ - libSDL (usually shipped with distro)
+
+ http://www.libsdl.org/index.php
+
+ - SDL_image
+
+ http://www.libsdl.org/projects/SDL_image/
+
+For para_slider, the zero memory widget library is neccessary. Get it at
+
+ http://www710.univ-lyon1.fr/~exco/ZMW/
+
+Finally, para_krell needs
+
+ - gtk2
+
+ http://www.gtk.org/
+
+ - gkrellm2
+
+ http://members.dslextreme.com/users/billw/gkrellm/gkrellm.html
+
+LICENSE:
+~~~~~~~~
+Distribution of paraslash is covered by the GNU GPL. See file COPYING.
+
+LIMITATIONS:
+~~~~~~~~~~~~
+The mysql database tool assumes that the basenames of your audio files
+are unique. If this is not the case, don't use this database tool,
+rename your files, or create your own database tool.

+README.mysql
+============
+
+This file describes how to use the mysql database tool which comes
+with the paraslash package.
+
+It assumes you have already installed mysql and paraslash as described
+in INSTALL, so read README and INSTALL before proceeding.
+
+First of all, make sure that
+
+ - mysqld is running
+ - para_server is running and compiled with mysql support (type
+ "para_client si" to find out)
+ - the user who runs para_client has the paraslash DB_WRITE and DB_READ
+ permissions set in server.users
+ - the user who runs para_server has create privileges on the mysql
+ server.
+
+Remember: If something doesn't work as expected, look at the server log file
+and/or increase output verbosity by using the -l switch for server and client.
+
+
+Specify mysql data (port, passwd,...)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Type
+
+ para_server -h
+
+and look at the mysql options. You may either specify these options
+in ~/.paraslash/server.conf or directly at the command line (not
+recommended for passwd option). Don't forget to do
+
+ chmod 600 ~/.paraslash/server.conf
+
+as this file contains the mysql passwd. To make these changes take
+effect you'll need to do
+
+ para_client hup
+
+Or, restart the server.
+
+Switch to the mysql dbtool
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Actually, the mysql database tool should already be selected (just
+ignore the warning about the missing database). To verify that it is
+indeed activated, type
+
+ para_client cdt
+
+which prints the name of the current database tool. If the dopey
+dbtool is still selected, try
+
+ para_client cdt mysql
+
+If this doesn't work either, it means that some required config options
+were not specified (check the log for more info) or that para_server
+was built without mysql support. Type
+
+ para_client si
+
+to find out. If mysql is not mentioned as a supported database tool,
+you'll have to recompile.
+
+
+Create a new database
+~~~~~~~~~~~~~~~~~~~~~
+
+Once the mysql database tool is selected, create the database:
+
+ para_client cdb
+ para_client cdt mysql
+
+The second command forces para_server to re-init the mysql dbtool.
+Check the log. There should not be any warnings or errors.
+
+
+Fill your database with content
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ para_client upd
+
+If this command fails, it most likely means the audio file directory
+(given in the server configuration file) does not exist, is empty,
+not readable, or contains different files with identical basenames. Fix
+this problem before proceeding.
+
+The command
+
+ para_client ls
+
+prints the list of all files known by the mysql dbtool. If the list
+is empty, double check the mysql_audio_file_dir option.
+
+
+Create a stream which selects all songs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To keep it simple, let's only define the stream "all_songs". See below for
+advanced stream usage.
+
+ para_client stradd all_songs < /dev/null
+ para_client sl 10 all_songs
+
+The latter command should show you ten filenames.
+
+
+Change to the all_songs stream
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ para_client cs all_songs
+
+You should now be able to start streaming with
+
+ para_client play
+
+
+Attribute usage
+~~~~~~~~~~~~~~~
+
+An attribute is simply a bit which can be set for each sound file
+individually. You may have as many attributes as you like. A new
+attribute "test" is created by
+
+ para_client na test
+
+and
+ para_client laa
+
+lists all available attributes. You can set the "test" attribute for
+the current song by executing
+
+ para_client sa test+
+
+or for any particular song by
+
+ para_client sa test+ filename
+
+You can unset the attribute "test" for the current song with
+
+ para_client sa test-
+
+and you can drop the test attribute entirely from the database with
+
+ para_client da test
+
+Stream usage
+~~~~~~~~~~~~
+
+A stream is a pair of expressions in terms of attributes and other
+meta data contained in the database. The first, boolian, expression
+determines the set of songs which are permitted in this stream. The
+second, integer, expression determines the order in which permitted
+songs are going to be fed to the audio file sender(s).
+
+To create a new stream called "my_stream", put arbitrary many (including
+none) accept or deny lines and one or zero score lines into some
+temporary file, say tmpfile. An accept/deny/score line consists of
+an identifier ("accept:", "deny:", or "score:"), followed by an
+expression. The command
+
+ para_client stradd my_stream < tmpfile
+
+adds the stream "my_stream" to dbtool's stream database.
+
+If the stream definition is really short, you may also just pipe it to
+the client rather than using temporary files. Like this:
+
+ echo "$MYSTREAMDEF" | para_client stradd my_stream
+
+
+Example:
+
+ Assume you already have an attribute "test" and you'd like to
+ to restrict the set of songs being played to those having the
+ "test" attribute set. Define a new stream "only_test" by
+
+ echo 'accept: IS_SET(test)' | para_client stradd only_test
+
+ Then, after switching to the "only_test" stream with
+
+ para_client cs only_test
+
+ only the desired songs are going to be played.
+
+There is no need to keep the temporary files containing the stream
+definition since you can always query the database to get it back:
+
+ para_client strq only_test
+
+The accept/deny expressions are used to find out which songs are
+permitted. The following four cases are all possible and valid:
+
+ o Neither accept nor deny lines: This selects all songs.
+
+ o Only accept lines: Songs that match at least one accept
+ expression are accepted, all others are denied:
+
+ accept_expr1 or accept_expr2 or ...
+
+ o Only deny lines: Songs that match at least one deny expression are
+ denied, all others are accepted:
+
+ not (deny_expr1 or deny_expr2 ...)
+
+ o Both accept and deny lines: A song is accepted if it matches
+ at least one accept expression, but no deny expression, i.e.
+
+ (accept_expr1 or accept_expr2 or ..) and not
+ (deny_expr1 or deny_expr2 ..)
+
+The command
+
+ para_client streams
+
+lists all available streams and
+
+ para_client strdel streamname
+
+removes the stream "streamname".
+
+There are more sophisticated ways to define a stream than just using
+one IS_SET() macro as in the example above. Of course, IS_SET(foo)
+is true for a given audio file if and only if it has the attribute
+"foo" set. Here are some more macros you can use:
+
+ o IS_N_SET(attr): True if attribute attr is not set
+
+ o NAME_LIKE(string): True if basename is like (in the sense
+ of mysql) "string"
+
+ o LASTPLAYED(): Expands to number of minutes that are gone
+ since this audio file has been played (by paraslash).
+
+ o NUMPLAYED(): Expands to number of times, the file has
+ been played.
+
+ o PICID(): Expands to the number of the picture which is
+ associated with this song.
+
+To give a real-life example, suppose you have already added the
+attributes "pop", "rock" with the "na" command. Assume also that you
+have set these attributes for some or all of your songs having the
+corresponding properties.
+
+If you like to be waked up in the morning by poprock songs, but you
+have some strange feeling telling you that just a few seconds of
+Madonna's voice will be enough to mess up your whole day, just write
+the lines
+
+ accept: IS_SET(pop) and IS_SET(rock)
+ deny: NAME_LIKE(%Madonna%)
+
+to some temporary file "tmp" and do
+
+ para_client stradd wake < tmp
+
+You can then switch to the new stream with
+
+ para_client cs wake
+
+or you can let cron do this for you on a daily basis..
+
+Accept/deny lines affect only the set of admissible songs, but not
+the order in which these songs are played. That's where the score
+expression comes into play.
+
+Scoring
+~~~~~~~
+You may put a single score line anywhere in the stream definition. If
+omitted, the default scoring rule specified in the configuration file
+applies. If there is no default scoring rule in the config file either,
+the compiled in default is going to be used (see para_server -h).
+
+Simple examples of scoring rules (either specified in a stream
+definition or as the default scoring rule in the config file) include:
+
+ LASTPLAYED()/1440
+
+This means that each song's score is just the number of days that went
+by since this song has been played (one day is 1440 minutes). This
+is fine in many cases since the dbtool then always chooses that
+admissible song, which wasn't played for the longest time.
+
+However, one disadvantage of this scoring sheme is that new songs,
+once played, are going to be deferred for a possibly very long period
+depending on the size of your collection of (admissible) songs. Hence
+the following scoring rule comes into mind:
+
+ score: -NUMPLAYED()
+
+since this gives newer songs, i.e. songs to which you haven't listen to
+that often, a higher score than older songs you already know by heart.
+
+You can also use a combination of these two methods:
+
+ score: LASTPLAYED()/1440 - 10 * NUMPLAYED()
+
+which subtracts 10 score points for each time paraslash has played
+this song.
+
+Another useful feature for scoring is due to the fact that "true"
+expands to one and "false" to zero. So you can also use the
+IS_SET/IS_N_SET/NAME_LIKE macros in a score line to give
+your favorite band "bar" some extra points:
+
+ score: 40 * IS_SET(foo) + 20 * NAME_LIKE(%bar%) + LASTPLAYED()/1440
+
+
+Pictures
+~~~~~~~~
+
+dbtool can also magage images that, when associated with certain songs,
+can be displayed by para_sdl_gui and para_krell when one of these songs
+is playing. It is also possible to just retrieve the current image via
+
+ para_client pic > filename
+
+in order to feed it to your favorite tool. Try
+
+ para_client help | grep ^pic
+
+and read the online help of the shown commands for more information.
