			#+TITLE: Auto-build package repository for Arch Linux

			* What is this?
			This is a set of files to auto-build a personal repository for Arch.
			It uses a chroot environment to build the packages, so that a build environment can be made on a server running a non-arch operating system.
			This is a package autobuild solution for Arch Linux.
			It supports the automated building of packages from the AUR.

			Currently it supports package signing and building clean from source.
			It can help to set itself up and generate GPG keys if need be.

			The chroot files are here from an older version of this project and are here as I think they're interesting.

			* Set-up
			Create a chroot environment named "chroot" in the current directory.
			Copy the ~build.sh~ script to ~/build/repo~ within the chroot.
			Script coming soon.
			Edit the variables at the top of ~main.sh~ to suit your repository details.
			Have a look at the init function near the bottom of the file to decide if you want to run it.
			If you decide to generate a GPG key, edit the name, comment and email so that it fits you.

			You may also want to set ~MAKEFLAGS="-j$(nproc)"~ within the chroot to enable parallel compilation.
			For xz compression, add the ~--threads=0~ option to COMPRESSXZ such that it reads ~COMPRESSXZ=(xz -c -z - --threads=0)~.
			ccache may be useful to decrease the times of git packages, due to the little changes.

			* Usage
			All scripts must be run as root.
			To enter the chroot, use the ~enter_chroot.sh~ script.
			To add a package from the AUR, use the ~add_package.sh~ script, with the git URL as the argument.
			To build the packages use the ~build_packages.sh~ script, which will enter the chroot, and build the packages from the PKGBUILDs stored in ~/build/repo~.
			The packages are built and put into the directory ~/build/repo/x86_64~, then pushed with git.
			Since git is used, be sure to sign in to git in the chroot and set ~git config --global credential.helper store~, with an appropriate remote repository.
			To enable automatic building, create a cronjob for root, something of the sort of ~* 12 * * * /path/to/dir/build_packages.sh~.
			To add a package ~main.sh add [package]~ should be run. Currently I only support adding one package at a time.
			To update all packages, use ~main.sh build-all~. A ~-f~ flag can be used to force a rebuild of all the packages.
			To allow automatic building, use a cronjob or write a systemd unit, there are many guides out there, although I may add examples if I feel like it.

			* To Dos
			# - Multiple packages from a single PKGBUILD :: Some PKGBUILDs can create many packages at once, currently I am unable to handle this.
			- AUR dependency checking and automatic resolution :: Something like what aurutils does, maybe I can steal it from there
			- Error catching for builds which fail. :: Have emailing, but nothing more advanced. Would be nice to have some basic error handling in the script
			# - Create a universal variables file :: Not sure how useful this would be, but could be nice
