+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 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.
+
+[This is the first released version of the Lesser GPL. It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+ This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it. You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations
+below.
+
+ When we speak of free software, we are referring to freedom of use,
+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 and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+ To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you. You must make sure that they, too, receive or can get the source
+code. If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it. And you must show them these terms so they know their rights.
+
+ We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+ To protect each distributor, we want to make it very clear that
+there is no warranty for the free library. Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+^L
+ Finally, software patents pose a constant threat to the existence of
+any free program. We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder. Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+ Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License. This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License. We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+ When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library. The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom. The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+ We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License. It also provides other free software developers Less
+of an advantage over competing non-free programs. These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+ For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it
+becomes a de-facto standard. To achieve this, non-free programs must
+be allowed to use the library. A more frequent case is that a free
+library does the same job as widely used non-free libraries. In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+ In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software. For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+ Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+ The precise terms and conditions for copying, distribution and
+modification follow. Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library". The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+^L
+ GNU LESSER GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+ A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+ The "Library", below, refers to any such software library or work
+which has been distributed under these terms. A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language. (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+ "Source code" for a work means the preferred form of the work for
+making modifications to it. For a library, 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 library.
+
+ Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it). Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+ 1. You may copy and distribute verbatim copies of the Library's
+complete 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 distribute a copy of this License along with the
+Library.
+
+ 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.
+\f
+ 2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, 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) The modified work must itself be a software library.
+
+ b) You must cause the files modified to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ c) You must cause the whole of the work to be licensed at no
+ charge to all third parties under the terms of this License.
+
+ d) If a facility in the modified Library refers to a function or a
+ table of data to be supplied by an application program that uses
+ the facility, other than as an argument passed when the facility
+ is invoked, then you must make a good faith effort to ensure that,
+ in the event an application does not supply such function or
+ table, the facility still operates, and performs whatever part of
+ its purpose remains meaningful.
+
+ (For example, a function in a library to compute square roots has
+ a purpose that is entirely well-defined independent of the
+ application. Therefore, Subsection 2d requires that any
+ application-supplied function or table used by this function must
+ be optional: if the application does not supply it, the square
+ root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Library,
+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 Library, 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 Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library. To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License. (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.) Do not make any other change in
+these notices.
+^L
+ Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+ 4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you 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.
+
+ If distribution of 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 satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library". Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+ However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library". The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+ When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library. The
+threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work. (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+^L
+ 6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License. You must supply a copy of this License. If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License. Also, you must do one
+of these things:
+
+ a) Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever
+ changes were used in the work (which must be distributed under
+ Sections 1 and 2 above); and, if the work is an executable linked
+ with the Library, with the complete machine-readable "work that
+ uses the Library", as object code and/or source code, so that the
+ user can modify the Library and then relink to produce a modified
+ executable containing the modified Library. (It is understood
+ that the user who changes the contents of definitions files in the
+ Library will not necessarily be able to recompile the application
+ to use the modified definitions.)
+
+ b) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (1) uses at run time a
+ copy of the library already present on the user's computer system,
+ rather than copying library functions into the executable, and (2)
+ will operate properly with a modified version of the library, if
+ the user installs one, as long as the modified version is
+ interface-compatible with the version that the work was made with.
+
+ c) Accompany the work with a written offer, valid for at least
+ three years, to give the same user the materials specified in
+ Subsection 6a, above, for a charge no more than the cost of
+ performing this distribution.
+
+ d) If distribution of the work is made by offering access to copy
+ from a designated place, offer equivalent access to copy the above
+ specified materials from the same place.
+
+ e) Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+
+ For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it. However, as a special exception,
+the materials to be 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.
+
+ It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system. Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+^L
+ 7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+ a) Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library
+ facilities. This must be distributed under the terms of the
+ Sections above.
+
+ b) Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining
+ where to find the accompanying uncombined form of the same work.
+
+ 8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License. Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library 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.
+
+ 9. 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 Library or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+ 10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+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 with
+this License.
+^L
+ 11. 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 Library at all. For example, if a patent
+license would not permit royalty-free redistribution of the Library 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 Library.
+
+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.
+
+ 12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library 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.
+
+ 13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser 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 Library
+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 Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+^L
+ 14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+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
+
+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+^L
+ How to Apply These Terms to Your New Libraries
+
+ If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms
+of the ordinary General Public License).
+
+ To apply these terms, attach the following notices to the library.
+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 library's name and a brief idea of what it does.>

NEWS
====
+---------------------------------------------
+0.4.3 (to be announced) "imaginary radiation"
+---------------------------------------------
+
+ - Fix an end-of-file detection bug in the oggdec filter.
+
+------------------------------------------
+0.4.2 (2010-04-23) "associative expansion"
+------------------------------------------
+
+It's been some time since the last release, but finally here is
+paraslash-0.4.2. The bulk of the changes comes from the new buffer
+tree API, but there are changes all over the tree. Mainly performance
+and usability improvements, but also quite some bug fixes.
+
+ - The new buffer tree API.
+ - DCCP: Support for CCID negotiation (Gerrit Renker).
+ - UDP robustness fixes.
+ - The --bufsize option for mp3dec is gone as it no longer makes sense
+ for the new buffer tree API.
+ - Fix audible buffer underruns for wma streams.
+ - The alsa writer no longer prints meaningless underrun durations.
+ - audiod: Defaults work also for udp streams. If no filter is
+ given for an audio format that is received via upd, fecdec is
+ automatically added as the first filter (along with the decoder).
+
+---------------------------------------
+0.4.1 (2009-12-22) "concurrent horizon"
+---------------------------------------
+
+Support for another audio format, minor feature enhancements and lots of bug
+fixes. All fixes that have been accumulated in the maint branch (in particular
+those mentionened in the 0.3.6 release notes) appear in this release as well.
+
+ - wma support.
+ - new afh option: --human to activate human-readable output.
+ - new server/audiod option: --log-timing to print timing information.
+ - build system improvements.
+ - source code documentation updates.
+
-------------------------------------
0.3.6 (2009-12-07) "cubic continuity"
-------------------------------------
- http/dccp: Do not send the audio file header twice.
- FEC: Timing improvements.
+----------------------------------------------
+0.4.0 (2009-11-10) "simultaneous independence"
+----------------------------------------------
+
+Two significant changes which require the new version number: The
+improved authentication dialog and the fact that the database code
+has been moved to a library, libosl. To use the new version, you have
+to generate new RSA keys, see INSTALL for details. A shell script is
+provided for conversion of the 0.3 database to the new 0.4 format.
+
+ - stronger crypto for client authentication
+ - the database code has been moved to a library
+ - improved status item handling
+ - cleanup of the build system
+ - The "-V" option now also prints the git version
+ - the new parser-friendly listing mode for the ls and stat commands
+ - mandatory rc4 encryption
+ - major audio format handler cleanups
+ - (id3,...) tags are no longer stored as a combined string in the database
+ - new mood methods: artist_matches, title_matches, comment_matches,
+ album_matches, year_maches, year.
+
--------------------------------------------
0.3.5 (2009-09-21) "symplectic separability"
--------------------------------------------

+para_server streams binary audio data (mp3/oggvorbis/m4a/wma files)
over local and/or remote networks. It listens on a tcp port and
accepts commands such as play, stop, pause, next from authenticated
clients. However, there are many more commands.
* rename detection. If files are moved or renamed, afs will
recognize them despite of this change.
-Despite of all these features, paraslash is lightweight. The
-stripped binary of para_server with all its features compiled in

para_client

para_write
a set of *mood lines* containing expressions in terms of attributes
and other data contained in the database.
-A mood defines a subset of audio files called the *admissible audio
-files* for that mood. At any time, at most one mood can be *active*
-which means that para_server is going to select only files from that
-subset of admissible files.

+for that mood. At any time, at most one mood can be *active* which

So in order to create a mood definition one has to write a set of
mood lines. Mood lines come in three flavours: Accept lines, deny
Takes no arguments and matches an audio file if and only if no
attributes are set.
- played_rarely
-
-Takes no arguments and matches all audio files where the number of
-times this audio file was selected is below the average.
-
- is_set attribute_name
+ is_set <attribute_name>
Takes the name of an attribute and matches iff that attribute is set.
- path_matches pattern
+ path_matches <pattern>
Takes a filename pattern and matches iff the path of the audio file
matches the pattern.
+ artist_matches <pattern>
+ album_matches <pattern>
+ title_matches <pattern>
+ comment_matches <pattern>
+
+Takes an extended regular expression and matches iff the text of the
+corresponding tag of the audio file matches the pattern. If the tag
+is not set, the empty string is matched against the pattern.
+
+ year ~ <num>
+ bitrate ~ <num>
+ frequency ~ <num>
+ channels ~ <num>
+ num_played ~ <num>
+
+Takes a comparator ~ of the set {<, =, <=, >, >=, !=} and a number
+<num>. Matches an audio file iff the condition <val> ~ <num> is
+satisfied where val is the corresponding value of the audio file
+(value of the year tag, bitrate in kbit/s, frequency in Hz, channel
+count, play count).
+
+The year tag is special as its value is undefined if the audio file
+has no year tag or the content of the year tag is not a number. Such
+audio files never match. Another difference is the special treatment
+if the year tag is a two-digit number. In this case either 1900 or
+2000 are added to the tag value depending on whether the number is
+greater than 2000 plus the current year.

Mood usage
help which is displayed by using the -h switch. The --detailed-help
option prints the full help text.
-para_fsck tries to fix your database. Use --force (even if your name
-isn't Luke) to clean up after a crash. However, first make sure
-para_server isn't running before executing para_fsck if para_fsck
-complains about busy (dirty) tables. para_fsck also contains an option
-to dump the contents of the database to the file system.
+If para_server crashed or was killed by SIGKILL (signal 9), it
+may refuse to start again because of "dirty osl tables". In this
+case you'll have to run the oslfsck program of libosl to fix your
+database. It might be necessary to use --force (even if your name
+isn't Luke). However, make sure para_server isn't running before
+executing oslfsck --force.
If you don't mind to recreate your database you can start
from scratch by removing the entire database directory, i.e.
- rm -rf ~/.paraslash/afs_database
+ rm -rf ~/.paraslash/afs_database-0.4
-Note that this removes all tables, in particular attribute definitions
-and data, and all playlist and mood definitions.
+Be aware that this removes all attribute definitions, all playlists
+and all mood definitions.
-para_fsck operates on the osl-layer, i.e. it fixes inconsistencies
-in the database but doesn't know about the contents of the tables
-contained therein. Use
+Although oslfsck fixes inconsistencies in database tables it doesn't
+care about the table contents. To check for invalid table contents, use
para_client check
-to print out bad entries, e.g.missing audio files or invalid mood
-definitions.
+This prints out references to missing audio files as well as invalid
+playlists and mood definitions.

+H:
+H: Options:
+H:
+H: -m Change grab mode. Defaults to sloppy grab if not given.
+H:
+H: -ms: sloppy grab
+H:
+H: -mp: pedantic grab
+H:
+H: -ma: aggressive grab
+H:
+H: The various grab modes only differ in what happens if the
+H: file descriptor to write the grabbed audio data to is not
+H: ready for writing (i.e. would block). Sloppy mode ignores
+H: the write, pedantic mode aborts and aggressive mode tries
+H: to write anyway.
+H:
+H: -p Grab output of node <parent> of the buffer tree.
+H:
+H: -n Name of the new buffer tree node. Defaults to 'grab'.
+H:
+H: -o One-shot mode: Stop grabbing if audio file changes.

+/**
+ * \file buffer_tree.h Buffer tree management.
+ *
+ * \par Buffer trees and buffer tree nodes.
+ * The buffer tree API offers a more powerful method than standard unix pipes
+ * for managing the data flow from the producer of the data (e.g. the network
+ * receiver) to its consumer(s) (e.g. a sound card).
+ *
+ * A buffer tree consists of buffer tree nodes linked via certain parent/child
+ * relationships.
+ *
+ * Each data buffer starts its way from the root of the buffer tree. At each
+ * node the data is investigated and possibly changed. New data is then fed to
+ * each child. Everything happens within one single-treaded process. There are
+ * no file descriptors and no calls to read() or write().
+ *
+ * Whenever a node in the buffer tree creates output, either by creating a new
+ * buffer or by pushing down buffers received from its parent, references to
+ * that buffer are created for all children of the node. The buffer tree code
+ * tries hard to avoid to copy buffer contents, but is forced to do so in case
+ * there are alignment constraints.
+ *
+ * Communication between nodes is possible via the btr_exec_up() function.
+ * For example, in para_audiod the alsa writer asks all parent nodes
+ * for for the number of channels and the sample rate of the current
+ * audio file.
+ *
+ * Buffer pools - An alternative to malloc/free buffer management.
+ *
+ * Non-leaf nodes usually create output to be processed by their children. The
+ * data must be fed through the output channel(s) of the node in order to make
+ * that data available to each child.
+ *
+ * The easiest way to do so is to malloc() a buffer, fill it, and then call
+ * btr_add_output(). This adds references to that buffer to all children. The
+ * buffer is automatically freed if no buffer tree node is using it any more.
+ *
+ * This approach, while being simple, has some drawbacks, especially affecting
+ * the root nodes of the buffer tree. Often the data source which is
+ * represented by a root node does not know in advance how much data will be
+ * available. Therefore the allocated buffer is either larger than what can
+ * currently be read, or is too small so that multiple buffers have to be used.
+ *
+ * While this could be worked around by using a large buffer and calling
+ * realloc() afterwards to shrink the buffer according to how much has been
+ * read, there is a second problem which comes from the alignment constraints
+ * of some filters, mainly the decoders like mp3dec. These need a minimal
+ * amount of data to proceed, and most of them even need this amount as one
+ * contiguous buffer, i.e. not spread out over two or more buffers.
+ *
+ * Although the buffer tree code handles this case just fine, it can be
+ * expensive because two or more buffers must be merged by copying buffer
+ * contents around in order to satisfy the constraint.
+ *
+ * This is where buffer pools come into play. Buffer pools try to satisfy
+ * alignment constraints without copying buffer content whenever possible. To
+ * avoid spreading out the input data over the address space like in the
+ * malloc/free approach, a fixed large contiguous buffer (the area) is used
+ * instead. A buffer pool consists basically of an area and two pointers, the
+ * read head and the write head.
+ *
+ * Once a buffer pool has been created, its node, e.g. a receiver, obtains the
+ * current value of the write head and writes new data to this location. Then
+ * it calls btr_add_output_pool() to tell much data it has written. This
+ * advances the write head accordingly, and it also creates references to the
+ * newly written part of the area for the children of the node to consume.
+ *
+ * Child nodes consume data by working through their input queue, which is a
+ * list of buffer references. Once the content of a buffer is no longer needed
+ * by a child node, the child calls btr_consume() to indicate the amount of
+ * data which can be dropped from the child's point of view. If no reference
+ * to some region of the buffer pool area remains, the read head of the buffer
+ * pool advances, making space available for the receiver node to fill.
+ *
+ * No matter if malloc() or a buffer pool is used, the buffer tree code takes
+ * care of alignment constraints imposed by the consumers. In the buffer pool
+ * case, automatic merging of references to contiguous buffers is performed.
+ * memcpy is only used if a constraint can not be satisfied by using the
+ * remaining part of the area only. This only happens when the end of the area
+ * is reached.

+ * Hence there are three different types of buffer tree nodes: The root node
+ * and the leaf nodes and nodes which have both a parent and at least one
+ * child. Such a node is called an internal node.
+ *
+ * Internal nodes represent filters through which data buffers flow, possibly
+ * while being altered on their way to the children of the node. Examples of

-## Script to convert the database of paraslash 0.2.x to version 0.3.x.
-##
-## Assumptions:
-## - para_server 0.2.x is running and the mysql selector is active
-## - para_server 0.3.x is running on another port
-## - The database of paraslash 0.3.x has been initialized (i.e.
-## para_client init has successfully been executed)
-## - All audio files in the mysql database of paraslash 0.2.x. have
-## already been added to the 0.3.x database (execute para_client add
-## /my/audio/file/dir to do that)
-##
-## The script converts the attribute table, the set attributes for each audio
-## file, the image table and all image ids, and finally the lastplayed and the
-## numplayed data.
-##
-## However, it does not convert the paraslash stream definitions from 0.2.x to
-## the moods of 0.3.x. You'll have to do this by hand.

-
- To use rbtrees you'll have to implement your own insert and search cores.
- This will avoid us to use callbacks and to drop drammatically performances.
- I know it's not the cleaner way, but in C (not in C++) to get
- performances and genericity...
-
- Some example of insert and search follows here. The search is a plain
- normal search over an ordered tree. The insert instead must be implemented
- int two steps: as first thing the code must insert the element in
- order as a red leaf in the tree, then the support library function
- rb_insert_color() must be called. Such function will do the
- not trivial work to rebalance the rbtree if necessary.
