# Global config file for buildpkg
#
# This file is designed to be sourced by pr. package buildscripts
# 

# Variables that *must* be overridden pr. package
# They are used to construct paths and more so they
# must have sane values
# topdir= The toplevel dir name under $buildpkgbase
#	 It is also used pr. default in the pkgname
#	  and it is also used pr. default as the toplevel name inside the sourcetar ($tarname)
# version= source version ie. 0.14.2b
# pkgver= the package revision, an increasing number is recommended but a date could be used instead
# source[0..x] = source filenames - source[0] *must* be defined and contain a legal filename
#		pr. default we will look for source[0] relative to $srcfiles
#		A filename that begin with / will be treated as absolute paths
#		Note! only source[0] will be automatically unpacked
# patch[0..x] = patch filenames - patch[0] must be defined but *can* be empty
#		pr. default we expect these to be listed relative to $srcdir
#		filenames that begin with / will be treated as absolute paths
#		All patching will be done from *within* $srcdir/$topdir directory with patch -p1
