Thanks a lot for this (also in TCL 6.3):
cadaver.tcz and davfs2.tcz added to repo
The cadaver.tcz of TCL 6.3 and TCL 5.2 seem to be the same --- however, when trying to connect using the https protocol in TCL 6.3 with openssl 1.0.1 I get an openssl library version mismatch.
Mounting with davfs2 works like a charm in TCL 6.3.
