I am porting a unix-based perl application to WinXP. My WinXP environment is polluted by a large commercial application that is beyond my control. This commercial app has three vintages of cygwin buried in it, the MKS toolkit, at least three perl installations, and numerous system and user environment variables.

To port my code, I've added yet another perl and cygwin. I've created scripts that clean up the environment before launching my code.

I have started writing a program to help wade through the mess. So far, it dumps the environment variables and some information from Config. I can imagine something much better. For example a program could parse perlrun, then look for perl-related variables in the environment, and explain them.

I welcome comments, pointers, suggestions, ideas, stories, or code that might help me along the way.

It should work perfectly the first time! - toma
