Yea, i am thinking about some README file.
Will add that later..

Thanks.
I have just uploaded a new version, with a slightly
modified version of your text.
http://web.telia.com/~u97007522/linux/code/mimeedit/

There are some other small changes too. I dscovered
that it bailed out when i hit a mimetype that i did not
have any registerd apps for. With the latest change i
get at least the option to add it. Not very well tested
though.

That is an error coming from a faulty generation of
the list, the "FALSE" word should not be seen and is
only telling zenity if an option should be checked.
FASLE means not checked. But if the list comes out
wrong, it ends up in the wrong column and is displayed.

The files used by gcmd or nautilus or whatever gnomeish
is the cache-file and those .desktop files. The defaults
list is not used for anything other than the creation of
the cache file. The first .desktop file mentioned for
a specific mimetype is the default one. And if you do not
have anything in your own cache, the system will use the
global one.

It looks more like mimeinfo.cache is not used at all, instead and all *.desktop files are scanned (but mimeinfo is not updated) and they seem to be mixed with another database  - probably the generic all-users /usr/share/applications. 

mimeinfo.cache (see above) This file is the one in control.
Or at least should be..

The mimeinfo.cache just points at .desktop files for a
specific mimetype. And if you do not have any mime that
fits in your own cache, the global will be used.
