Which tutorials would you recommend? I know how to write a module; my problem is not knowing how to make it available without conflicting in some way with PPM (something I use without understanding). The only two that look as though they might be relevant to PPM are Installing CPAN on a Windows system, which doesn't help as I don't want to buy Visual Studio, and HowTo build and distribute a PPMed module for Win32, which is about making packages for PPM. Again, I don't - I just want to avoid conflicts. By the same token, I have no plans to release on CPAN, and am highly nervous of any book that doesn't profess in bold type that all species of U*x will be ignored utterly. I'm very much writing for Excel, and while I accept that Linux is better, I need Messware solutions and have too much experience of documentation that claims to be polyglot but is utterly incompatible with Messware in general and ActiveState in particular.
