Aha... This is pretty weird, in light of the prescription on the website:

Shared MIME database package

The core database and the update-mime-database program for extending
it are available from the [WWW]software pages.

If you have added types that should go in the common freedesktop.org
base list of types, you should create an enhancement request on
[WWW]the MIME bugtracker with your new XML file.

If the procedure is different, perhaps we should ask them what it is?
I don't think we have a real problem with maintaining a "freedesktop"
subdir somewhere in the sources since it appears to cover quite a wide
range of systems, but we don't seem to know what to do with it.

The procedure appears to be different between Linuxen: On SUSE, I get

viggo:~/>rpm -qf /usr/share/mime/text/x-texinfo.xml

whereas FC4 has

[pd at janus ~]$ rpm -qf /usr/share/mime/text/x-texinfo.xml
file /usr/share/mime/text/x-texinfo.xml is not owned by any package

(and likewise 60-odd other .xml files). So it seems that SUSE collects
all this stuff in a single RPM and FC4 lets it be handled by the
post-install mechanism (on each package or by "exploding"
freedesktop.org.xml ??)

My inclination would be to stick with .R, possibly adding .r to guard
against Windows case-folding issues, but .r used to be Ratfor files.
.q/.s/.S are used by some people supporting both R and S-PLUS, but I
don't think they care how such files are displayed by Nautilus and

OK, modulo case-fold

Why the RDX2 bit?? We do have .RDA from windows, too.

.Rout, please. Also .Rout.save and .Rout.fail. (And it's not just
ESS that creates them).


6. Rprofile files .Rprofile or Rprofile.

Some fun potential with gedit/Kate plugins too (ESS for the 21st
century anyone?)
