+To add a file to the source tree, just create it. The Makefile will automatically discover it, compile it, and link it. Consequently, files that do not belong into the CP2K libraries must end on an ignored suffix.
+The file discovery is based on a simple suffix naming convention:

-===== Packages =====
+Furthermore, the code base is structured into [[packages]].
-The code base is structured into directories. Every directory has to contain a file called ''PACKAGE'' . A typical ''PACKAGE'' looks like this:
-<code python>
-{
-"description": "Smart process pinning",
-"requires": ("../common", "../dbcsr", "../machine", )
-}

-The entry ''requires''  list all the directories on which the code in the current directory may depend upon. This means, modules in the current directory may only use modules from the listed directories. The requirements between directories must **not** have cycles.

+The Makefile allows to compile multiple versions of all build targets in parallel:
