shared-mime-info: update-mime-database related question

[Jerome Leclanche]

Packages ship their mime types in /usr/share/mime/packages. The
default mime types are shipped in
/usr/share/mime/packages/freedesktop.org.xml. These are xml files
containing all the mime types shipped by the application by its name.
update-mime-database "splits" it into the /usr/share/mime
subdirectories and builds some other cache files and such in that
directory.
