How do I set GNUMERIC 1.2.12 to always Save As excel .xls, etc.?

[Chris-likes-Linux]

Hi,

I'm converting some Windows users to Linux and I need them to be able
to exchange Excel spredsheets with others _without_ having to remember
to 'Save As' .XLS manually. It seems that this works if they
_receive_ a file from Excel, ... but how do I set Gnumeric to always
use a particular format when a new workbook/file is created?

I saw the post about setting plugin.xml, but that seems only to be
true for the much older 0.65 release(!?).

Thank you.

Edit
<prefix/lib/gnumeric/1.3.1/plugins/excel/plugin.xml
or if you build from sources
gnumeric/plugin/excel/plugin.xml.in

And add
default_saver_priority="51"
to the exporter you want as the default. Any value > 50 will work
to override the xml dom importer.
