gEDA-dev: SPICE rawwaveform file

[michel agoyan]

In fact I'm looking for a binary format because it is more compact than 
a text file.
I simple have an huge amount of waveforms to deal with coming from a 
digital scope.
I want to process them  (average correlation ...) and write the results 
using a format
that is compact and that allows the use of waveform viewer such as gwave.

The suggestion of Werner seems to be the right one . Finally the  source 
code is the best documentation
that I could retrieve :-) .
Thanks for your help.
