- the cut and paste between file and dir conditions is always a bad thing - i made one function (hg_version) to basically call and parse hg - i made a function to include the cases of what might be returned by imp.find_modules (_input_id) - the check for a .hg folder was insufficient. Lots of things could go wrong. Instead I use the return code from the Popen process. The return code catches this and any other problem that hg runs into. - its easier to offer more rcs support in future (cvs,svn,git)
