Thanks, I wasn't aware of this file.  The file is not very parser
friendly, compared with the INDEX file :)

I could use it as a workaround:  If no pkgsrc tree is found, check for
the pkg_summary file and download it if necessary.  Then pkg_search
could perform a only basic search.  Maybe it should output the path to
the server to install the binary package?

Check the attached path against HEAD.  I also updated my email address
:)

Regards,

	Matthias
