appwav - append multiple waveform files to single file.
appwav [-NAME ] infile1 infile2 ... outfile
appwav() copies the contents of all input files to a single
output file. Normally, all segments defined within each input file are
retained in the output file, with logic removing name collisions by
mangling the segment names where necessary (usually adding one or more
digits onto the end of any duplicate segment names to create unique
names). However, this behaviour is altered by use of the -NAME flag
The name of each input file (up to 6 characters) is used as the name
of a segment in the output file corresponding to the input file.
