True.

But it really is annoying when you download the latest-and-greatest release of a package only to find out it doesn't compile on your OS of choice, and even worse when you find out it is because of new code that you will never use which was added in just before the release went final!

I can't help you with spaghetti, but the Qt folks did make their Perforce importer available. Chris Lee put it in the fast-export project on repo.or.cz. Its a relatively short Python program. Might help you get started.

They created annotated tags (with no message) for every p4 changeset. I think its just because they didn't realize you can use (abuse?) the `reset` command in gfi to create lightweight tags instead.

I actually implemented a "data <path" command in gfi to tell gfi to load data from a file, for this type of case where the foreign system has dropped the files in your working directory and you just want Git to read them.

But there's no synchronization between gfi and the frontend (aside from the pipe buffer throttling the frontend), so there is no way for the frontend to know that gfi has finished a batch of files and its safe to ask p4 for the next revision.

So I threw it away.  It was only a 10 line patch anyway.  :)
