"""Initialize MaxQuant tool for use with a new version of
modifications/enzymes.xml.

TODO: Append function: only add modifications that are not
already present, add modification entries to conda maxquant

Authors: Damian Glaetzer <[e-mail]>

Usage: init.py [-a] [-m MODS_FILE] [-e ENZYMES_FILE]
FILES are the modifications/enzymes.xml of MaxQuant, located at
<ANACONDA_DIR>/pkgs/maxquant-<VERSION>/bin/conf/.
(for conda installations)

Updates modification parameters in macros.xml.
