The relax language definition is now auto-generated by the fetch_docstrings.py script.
This is for use in the relax user manual using the listings package. The fetch_docstrings.py
script now creates the docs/latex/script_definition.tex file. This is used by the relax.tex file
via an \include{} statement. This setup allows all of the relax user functions to be dynamically
set as keywords for the relax language definition.
