Re: Meld 1.1.4: Question regarding paths.py

["Stephen Kennedy" <stevek gnome org>]

Hi Andreas, it's probably clearer if you get the meld source tarball.
The way I've done it, you can run directly from untarred source
without having to install.

Your modifications would mean that if there was a version already
installed on your system, then you could not download and check out
the latest version without clobbering the installed version.

I often wish all python packages had this facility when I'm deciding
whether it's worthwhile to install them or not.

Stephen.
