[CM] extract track regions

[Rodrigo Segnini]

Hi gurus.
I have some audio files several minutes long. Each file has instrument 
samples separated by silence. Both, the samples and the silences have 
variable duration.
I want to extract each sample as an independent file automatically, so I 
want to keep in the new file name some reference to the original long 
file.
I kind of see this possible in snd, so I wonder if someone has done this 
already.
Thanks,
Rodrigo
