1# Debian package renaming only occurs when a package is built
2# We therefore have to make sure we build all runtime packages
3# before building the current package to make the packages runtime
4# depends are correct

6# Custom library package names can be defined setting
7# DEBIANNAME_ + pkgname to the desired name.

9# Better expressed as ensure all RDEPENDS package before we package
10# This means we can't have circular RDEPENDS/RRECOMMENDS
