ssconvert (cmdline spreadsheet format conversion)

[Jody Goldberg <jody gnome org>]

Enough people have asked for this, and it was so easy to add that
I've added a basic implementation to CVS that will be included in
the next release (1.2.1).  There are lots of bells and whistles that
could be added so please have a look and send in a patch or two.

It can map from any of gnumeric's supported importers to any of its
available exporters.  The main limitation is that there is currently
no provision for importer or exporter specific flags.  That would
make a nice extension.
