Re: [aur-general] [PATCH] initial support for any architecture.

11 Mar 2009

      I've also written a script, convert-to-any which takes the name of
a package like this:
   convert-to-any community/pitivi
and converts it into an arch-independent package. It also updates the repository
databases accordingly, creating the 'any' folder in the repository if
needed. This
script requires dbscripts. However, this script does not make the repo-any dir
in SVN.

#!/bin/bash
# Converts an existing package into an
# architecture-independent package and updates
# the repositories accordingly.
