Re: gnucap error

Thanks Al for your response. It is a pleasure to have feedback from the 
autor of GNUCAP. Congrats!

Oh, I am using gnucap 0.35 from Debian Stable. I will install latest 
snapshot and see. I watched the page and saw that 0.35 was the stable 
release and thought that no improvements were made since that.

http://www.gnucap.org/devel/

latest one seems to be from 2009-12-07. is it the right one?


Thank you very much and congrats for this great software
