6 The server process listens on a network socket and accepts connections
7 from para_client or para_audiod. For the connection to succeed the
8 connecting peer must authenticate as one of the users stored in the
9 user table of para_server. Each entry of the user table contains the
10 set of permission bits that are granted to the user. Authenticated
11 users may execute one of the commands below if the set of permission
12 bits of the command is a subset of the permission bits that are
13 granted to the user.

16 [subcommand add]
17 purpose = add or update audio files
18 non-opts-name = path...
19 aux_info = AFS_READ | AFS_WRITE
20 [description]
21 Each path must be absolute and refer to either an audio file or a
22 directory. In case of a directory, all audio files in that directory
23 are added recursively. Note that the given paths refer to files or
24 directories on the host on which para_server is running.
25 [/description]
26 [option all]
27 short_opt = a
28 summary = add all files
29 [help]
30 The default is to add only files ending in a known suffix for a
31 supported audio format.
32 [/help]
33 [option lazy]
34 short_opt = l
35 summary = add files lazily
36 [help]
37 If the path already exists in the database, skip this file. This
38 operation is really cheap. Useful to update large directories after
39 some files have been added.
40 [/help]
41 [option force]
42 short_opt = f
43 summary = force adding/updating
44 [help]
45 Recompute the audio format handler data even if a file with the same
46 path and the same hash value exists.
47 [/help]

65 Report stale paths and invalid image and lyrics ids of the audio
66 file table.
67 [/help]
68 [option attribute]
69 short_opt = A
70 summary = check for invalid attributes
71 [help]
72 Report audio files whose attribute bitmask is invalid, i.e., has a bit
73 set which does not correspond to any attribute of the attribute table.
74 [/help]
75 [option mood]
76 short_opt = m

91 aux_info = AFS_READ | AFS_WRITE
92 [description]
93 If no option, or only --verbose is given, all fields of the audio
94 file selector info structure are copied to each row of the audio file
95 table whose path matches at least one of the given patterns. Otherwise,
96 only those fields which correspond to the given options are copied.
97 [/description]
98 [option attribute-bitmap]
99 short_opt = a
100 summary = copy the attribute bitmap
101 [option image-id]

117 [subcommand ff]
118 purpose = jump N seconds forward or backward
119 synopsis = n[-]
120 aux_info = VSS_READ | VSS_WRITE
121 [description]
122 This sets the 'R' (reposition request) bit of the vss status flags
123 which enqueues a request to jump n seconds forwards or backwards.
124

139 called with a command name as first argument, it prints the description
140 of this command.
141 [/description]
142
143 [subcommand hup]
144 purpose = reload config file, log file and user list
145 aux_info = VSS_WRITE
146 [description]
147 Reread the config file and the user list file, close and reopen the log
148 file, and ask the afs process to do the same. Sending the HUP signal
149 to the server process has the same effect as running this command.

151
152 [subcommand init]
153 purpose = initialize the database tables for the audio file selector
154 synopsis = [table_name...]
155 aux_info = AFS_READ | AFS_WRITE
156 [description]
157 When invoked without arguments, this command creates all
158 tables: audio_files, attributes, scores, moods, lyrics, images,
159 playlists. Otherwise only the given tables are created.

179
180 [option id-sort]
181 short_opt = i
182 summary = sort attributes by id
183 [help]
184 The default is to sort alphabetically by name.
185
186 Attributes are internally represented as an 64 bit array. The attribute
187 id is the bit number in this array.
188 [/help]
189 [option long]
190 short_opt = l
191 summary = print long listing
192 [help]
193 The long listing prints the attribute id in addition to the name of
194 the attribute. The id is printed as a decimal number and is separated
195 from the name by a tab character.
196 [/help]
197 [option reverse]
198 short_opt = r
199 summary = reverse sort order
200
201 [subcommand mvatt]

213 aux_info = VSS_READ | VSS_WRITE
214 [description]
215 Set the 'N' (next audio file) bit of the vss status flags. This
216 instructs the server to close the current stream, if any. The 'P'
217 (playing) bit is not modified by this command. If it is on, playing
218 continues with the next audio file.
219
220 This command is equivalent to stop if paused, and has no effect
221 if stopped.
222 [/description]
223
224 [subcommand nomore]
225 purpose = stop playing after current audio file
226 aux_info = VSS_READ | VSS_WRITE
227 [description]
228 Set the 'O' (no more) bit of the vss status flags which asks
229 para_server to clear the 'P' (playing) bit after the 'N' (next audio
230 file) bit transitions from off to on (because the end of the current
231 audio file is reached). Use this command instead of stop if you don't
232 like sudden endings.
233 [/description]
234
235 [subcommand pause]
236 purpose = suspend the current stream
