22usage: abcde.py [options] [tracks]
23Options:
24-1 Encode the whole CD in a single file
25-a <action1[,action2]...>
26 Actions to perform:
27 cddb,read,normalize,encode,tag,move,replaygain,playlist,clean
28-b Enable batch normalization
29-c <file>
30 Specify a configuration file (overrides system and user config files)
31-C <discid#>
32 Specify discid to resume from (only needed if you no longer have the cd)
33-d <device>
34 Specify CDROM device to grab (flac uses a single-track flac file)
35-D Debugging mode (equivalent to sh -x abcde)
36-e Erase encoded track information from status file
37-f Force operations that otherwise are considered harmful. Read "man abcde"
38-g Use "lame --nogap" for MP3 encoding. Disables low disk and pipes flags
39-h This help information
40#-i Tag files while encoding, when possible (local only) -NWY-
41-j <#> Number of encoder processes to run at once (localhost)
42-k Keep the wav tracks for later use
43-l Use low disk space algorithm
44-L Use local CDDB storage directory
45-n No lookup. Don't query CDDB, just create and use template
46-N Noninteractive. Never prompt for anything
47-m Modify playlist to include CRLF endings, to comply with some players
48 WARNING: Deprecated. Use \"cue\" action
49-o <type1[,type2]...>

51-p Pad track numbers with 0's (if less than 10 tracks)
52-P Use UNIX pipes to read+encode without wav files
53-q <level>
54 Set quality level (high,medium,low)
55-r <host1[,host2]...>
56 Also encode on these remote hosts
57-R Use local CDDB in recursive mode
58-s <field>
59 Show dielfs from the CDDB info (year,genre)
60-S <#> Set the CD speed
61-t <#> Start the track numbering at a given number
62-T <#> Same as -t but modifies tag numbering
63-U Do NOT use UNICODE (UTF8) tags and comments
64-v Show version number and exit
65-V Be a bit more verbose about what is happening behind the scenes
66-x Eject CD after all tracks are read
67-w <comment>
68 Add a comment to the CD tracks
69-W <#> Contatenate CDs: -T #01 -w "CD #"
70-z Use debug CDROMREADERSYNTAX option (needs cdparanoia)
71
72Tracks is a space-delimited list of tracks to grab.
73Ranges specified with hyphens are allowed (i.e., 1-5).
