## Programming language, Tools and Libraries
-The core of PROJECT is written in C (gcc or clang supported). A few
-non-essential scripts are implemented in Perl and Python. PROJECT requires
-the following tools to build distribution packages: automake, autoconf,
-texinfo, libtool and gawk and various libraries (i.e. libpam and libjson-c).

If your contribution requires a new library or other tool, then please
-highlight this in your description of the change. Also make sure it’s
-supported by all PROJECT platform OSes or provide a way to build without the
-library (potentially without the new feature) on the other platforms.

automatically tested by one or more CI systems. Only after this test succeeds

New files need to have a Copyright header (see [License for

defined (watch your `AC_DEFINE`s).

CLI's are a complicated ugly beast. Additions or changes to the CLI
should use a DEFUN to encapsulate one setting as much as is possible.
