Hi,

It fails on debian sid because 'gs -v' returns GPL Ghostscript SVN

Anyway, the parser will be ugly because it has to deal with version
numbers like '7.07.1'.
Should I propose a trivial patch to get thinks working on debian sid ?

ps :Why is there no standard way (like -v or --version) on *unix to get
the version *number*?? Only the version number. Why :(

This was fixed a while back in svn, but thanks for the report. It turns out
that --version does return only the version number.

Unfortunately, I'm not able to get the svn version working :
