reisefill is a project to simplify filling out pdf forms.
Two scripts are available:
• fillform: fills a pdf form by asking you questions
• readformdata: helps for creating config files that can be used by fillform
Both have some help available via the option --help/ -h.
The configuration file syntax is decribed in doc/configspecification.

Prerequisites:
  for fillform one needs the python module fdfgen.

  pip3 install fdfgen
  or copy the file https://github.com/ccnmtl/fdfgen/blob/master/fdfgen/__init__.py
