very basic checking so far

#!/bin/bash

if [ ! -f PKGBUILD ]; then

	echo "This must be run in the directory of a built package."

	exit 1

source PKGBUILD

if [ ! -f $pkgname-$pkgver-$pkgrel.pkg.tar.gz ]; then

	echo "You must have a built package to check."

	exit 1

pkgurl=`yes | pacman -Sp $pkgname | rev | cut -d ' ' -f 1 | rev`

oldpkg=`strip_url $pkgurl`

if [ ! -f $oldpkg ]; then

	wget $pkgurl

fi

tar tzf $oldpkg > filelist-old

tar tzf $pkgname-$pkgver-$pkgrel.pkg.tar.gz > filelist

sort -o filelist filelist

sort -o filelist-old filelist

diff filelist-old filelist
