# usage: vcfromfilename [options] <files>
|
|
# options:
|
|
# -n: Only set the track number
|
|
#
|
|
# Adds Vorbiscomment data to ogg vorbis and flac files based on the filename.
|
|
# Files should be in darkside's arbitrary file name standard, which is:
|
|
# album/artist-tracknum-title.(ogg|flac)
|
|
#
|
|
# Requires vorbiscomment and metaflac
|
|
#
|
|
# Changelog:
|
|
# 0.2.2: added flac support
|
|
# 0.2.1: fixed version in help message
|
|
# fixed handling of dashes in artist name and title
|
|
# 0.2: aligned version with ds-audiotools
|
|
# 0.1.1: added version variable
|
|
# 0.1: initial implementation
