><P
>These routines provide conversion of information based on a source and
target mime type. They return -1 on failure, or an opened file
descriptor with the data on success</P
><P
>The rules for converting from one MIME type to another are
loaded from the <TT
CLASS="FILENAME"
>$gnome-prefix/share/type-convert</TT
>
directory. Any files in that directory whose extension is
<TT
CLASS="FILENAME"
>.convert</TT
> is loaded as well as the per-user
<TT
CLASS="FILENAME"
>~/.gnome/type.convert</TT
> file.</P
