## About the setup

## Requirements

## Installation

### From Source

For all non-ArchLinux systems you can install the software the old way by

building it from source (`make build`) and fire a `make install`. The project

is not configured by autotools, but the makefiles makes use of the [standard

directory variables][]. Forthermore you can specify a `DESTDIR` variable for

packaging.  (`make DESTDIR=/tmp/xyz install`) If you are interessested in

changing the default directory variables consider the [Makefile.shared

file](Makefile.shared). They are change able the same way as `DESTDIR`. The

`uninstall` target takes care of the same variables and will cleanup your

system if you don't want the software to be installed.

:warning: This process expects you to build the software on the same

architecture as it will run on. For cross compiling consider a related guide

for your target architecture.

### ArchLinux Packaging

If you are interessested in building an ArchLinux package, all you have to do

is to clone this repository, install/build all the dependencies of the project

and run `makepkg` inside the `dist/archlinux` directory. Afterwards you will

find a fresh package (`avm-motion-trigger-*-*.pkg.tar.xz`) in the same

directory. This process underlies the same cross compiling restrictions as the

[From Source](#from-source) installation.
