A simple dirty wrapper script that downloads the latest
upstream chromium devel builds (for Ubuntu) and provides
naughty Netscape library symlinks for compatibility
and pulls in fedora deps (for x86_64 installs),
and a command and desktop file to run it.

Here is a yum repo configuration:

[chromium-get-snap]
name=Chromium devel builds scripts
