I was looking at some Win32 perl modules on CPAN recently - specifically, I need some functionality that is provided by perl's Win32::GuiTest module. From what I can tell, most of the code involved is actually C code - they have C wrappers of some Win32 system calls, etc. and then they build on them - mostly all in C, only one of the funtions was actually written in Perl. But there's a catch, the code they provide is actually not the original C code , but the .xs files which are presumably read by XS (kind of like SWIG, but specifically for extending Perl). Now, I could be wrong, but the XS code (somecode.xs) looks mostly like C code with some added tags. Might it not be possible (and somebody who is more familiar with XS than I could shed some light here) to take the .xs files and munge them somehow to create Ruby extentions - or at least to make them readable from SWIG and then create Ruby modules from that direction. It seems like doing this could get us a good number of Perl modules (at least where the modules rely heavily on C code) fairly quickly. Phil
