looking for open source CalDAV client

<originally posted to ietf-caldav>

any open source CalDAV client projects going on out there?

i'm looking for a simple command line tool to help with developing and
testing our server. unfortunately neither curl nor lwp-request seem to
support arbitrary HTTP methods, so they won't be immediately useful.

the perldav project (<http://www.webdav.org/perldav/>) doesn't seem to
have been active in years, but it looks to have a good base to build on.
i've contacted the author but haven't heard back yet.

if nobody has anything more substantial, i'll probably hack together
something based on perldav. if anyone's interested in helping out, let
me know.

thanks!
