They have some perl modules for Unix, and I wrote a quick script hack for Win32 Perl which is in the Code Catcombs. I don't actually know what they charge, but I set it up for someone else and it's pretty easy.
thanks $code or die - if anyone else has recommendations of other vendors (specifically UK ones) offerring Perl libraries, this would be appreciated.
Also if anyone has experience of problems with reliability, security, etc (or buggy Perl libraries for that matter) then this would be great to know in advance.
