- partially based on a concept by FhG IIS, Erlangen
- and edited by
- in the course of development of the MPEG-2 NBC/MPEG-4 Audio standard
- ISO/IEC 13818-7, 14496-1,2 and 3. This software module is an

- 10-jun-96 HP ...
- 13-jun-96 HP changed ComposeFileName()
- 19-jun-96 HP changed ComposeFileName()
- 20-jun-96 HP added NOTE re CmdLineParseString()
- 08-aug-96 HP changed string handling in CmdLineParseString()
- changed handling of variable length argument list
- added CmdLineEvalFree(), CmdLineParseFree()
- 09-aug-96 HP ...
- 26-aug-96 HP CVS
