 The _ecal-base-archlinux_ container may be used if you want to build eCAL yourself locally within an Arch Linux environment. The _ecal_base-archlinux-aur_ container pulls in the [AUR package](https://aur.archlinux.org/packages/ecal/) and is meant as a clean build environment for pushing new AUR package versions.

+## Note on package managers
+The _ecal_ image uses *make install* instead of the package manager of the base OS; this makes the Dockerfile easier, but is of course no clean way to provide a dependency if a dependent program or image relies on an installed Debian or Arch Linux package. In such cases, you will need to either install a dummy package yourself or call your package manager with the correct flag to make it assume a package as installed.
