[LAU] setting a samples loop points on command line

Hi

Suppose I have an un-looping sample that I know will loop glitchfree
with loop start set to x and loop end set to y (x and y in samples). How
can I set those points in the sample (I guess it's actually in the
header) from the commandline?

I'd love to do it with ecasound, since I already use that in the python
script I'm working on...

Is it possible to modify the header directly or it's that asking for
trouble?
