"""
|
|
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)
