 The parser is designed to be usable also outside the NoMaD project as a
 separate python package. This standalone python-only mode is primarily for
 people who want to easily access the parser without the need to setup the whole
-"NOMAD Stack". It is also used when running unit tests. The nomadtoolkit
-package is currently used by the developer only and is thus not available
-through gitlab. Here is an example of the call syntax:
