Hmmm. It feels a little heavy-handed to modify the PATH for each potential script/executable after a recursive search, considering I technically know where they are stored (in the directory of the calling project/script, given a heirarchy of projects).

On top of that, since I don't know it explicitly (that's pretty much the entire problem here!), $startdir will always be the cwd, too (or at least $FindBin::Bin), which would be redundant if PathStuffer is used multiple times (the search is probably a negligable impact in this day and age, but still. ;) ).

Also, it's not always the case that a file will be a script (note that 'rdiff' is an executable binary), so just searching for ".pl" doesn't quite cover all use cases. Since *nix binaries don't really have naming conventions (and hence I'd have to search for ".*"), I'd necessarily be including every directory into the path to include it, which just makes me feel dirty. (It probably wasn't obvious that I'm using *nix boxes here, but I'd like to keep the code portable either way)

That said, this is certainly still a viable option that I wouldn't have considered otherwise :)
