The "DHParser/templates" sub-directory contains templates for python scripts
that are generated by DHParser when creating a new project. Usually, this is
done by substituting placeholders withing the template like "{name}" via
the format()-method of Python's string type.
Scripts are being generated within these modules:
- DHParser/srcipts/dhparser.py
- DHParser/dsl.py
- DHParser/ebnf.py
