Sun May 8 16:19:34 2005 UTC (14 years, 9 months ago) by schoenebeck
File size: 5054 byte(s)
* added functions libraryName() and libraryVersion() to each of the three
  library units (RIFF,DLS,gig)
* all tools now offer a command line switch -v to show the tools revision
  and the used libgig version
* man pages are now auto generated with the correct libgig version
