For example, if an application installs information about a new MIME type to /usr/share/mime/packages/diff.xml, then update-mime-database must be called with the parameter /usr/share/mime.
Adibidez, aplikazio batek MIME mota bati buruzko informazioa instalatzen badu /usr/share/mime/packages/diff.xmlen, /usr/share/mime parametroarekin deitu behar da update-mime-database.
