Code review comment for lp:~brendan-donegan/checkbox/bug916859_record_playback

In that case, since this seems to be the one and only Perl script in checkbox, we should at least add the corresponding package name to the Recommends line in the debian/control file. It doesn't strictly need to be in the Depends line because only a script depends on that package. By the way, I'm not sure whether the package should be expressed as just "perl" or something more esoteric like "${perl:Depends}".
