"""
This is an even simpler script to combine multiple mimeapps.list files into
one.
This is not too trivial, since an addition can be reverted by a deletion in a
later file and vice versa, and all values should probably be deduplicated.
The input files are processed left-to-right. This means that the default is
taken from the leftmost (first supplied) file the respective MIME type is
specified (other files serve as fallbacks), but an association added in one
file can be reverted in a later file (and possibly re-added in even later file)
