# 2002/04/11 v0.1.0: first version
# 2002/04/12 v0.1.1:
# 2002/04/14 v0.1.2:
# - handles now multiple vcd's
# - support's mp3 audio as option
# - use of mp2enc/lame instead of toolame because of support
# of resampling and mp3
# 2002/04/16 v0.1.3:
# - new option "-burnonly"
# - new option "-vbr"
# - removes mpg file after mastering cd image
# (mplayer can read bin images!)
# - bugfixes
# 2002/04/22 v0.1.4
# - bugfixes / changes
# - more options
# 2002/05/06 v0.1.5
# - new option "-norm"
# 2002/05/08 v0.1.6
# - bugfixes
# - new option "-vfr"
# - "-norm" renamed to "-vnorm"
# 2002/05/15 v0.1.7
# - bugfixes
# - more help
# 2002/05/26 v0.1.8
# - new option "-sync"
# 2002/06/19 v0.1.9
# - new option "-mpgonly"
# 2002/09/21 v0.1.10
# - bug fixes
# - tests now, if the commands are in path and give warnings
# and errors.
# 2002/11/01 v0.2
# - bug fixes
# - new options: "-sox", "-volume", "-toolame"
# - renamed "-mpg" to "-mpegsrc"
# - default cd size changed to 800mb
# 2002/11/18 v0.2.1
# - aspect ratio for vcd's, too
# - pulldown mode...
# 2002/12/01 v0.2.2
# - -normalize
