I've taken this and made it more complicated :( I'm interested in suggestions for improvements!

It will now keep "local" repositories in the list if they are alive, even if they aren't in the PPM::Repositories list or one of ActiveState's.

It preserves the order of "local" repositories. (Those added from PPM::Repositories are still added in key order.)

Since this script would generally be run only occasionally, it also gets the latest PPM::Repositories, in case that list has been updated. I could only mangle^Wmanage this automatically by first removing the old module, and then installing it again. If this somehow fails to reinstall, the script won't load. (I could fix this, but I've run out of time today. Besides, it winds up being something of a circular dependency.) This can be avoided by calling it with some arbitrary argument.

adds and deletes now only happen if necessary (according to the IN_LOCAL_LIST key in the script-generated %repositories hash).

I also found that exec in Windoze caused the prompt to wait for user input, such that it never appeared to finish. Switching to system with appropriate control logic fixed it.

I'm sure someone will want option processing, etc., but I'm not inclined to add that today ;)

Update: Thanks to randyk, used PPM::UI instead of ppm rep describe $name.
