This software was developed and tested with the textual framework in version 0.15.1.
Though it might already be quite useful, fimf is currently still in "alpha" status, i.e., it is probably buggy. Please make a backup of your data files before manipulating them with fimf. Also, search-and-replace across many files can go wrong (due to bugs or due to user input) and there is no undo button in fimf.
Development mode: Clone the repo and run pip install -e . from within that directory.
Normal usage mode: pip install fimf.
Call fimf (the textual user interface (TUI) should be self-explanatory).
