[Svnmerge] svnmerge newbie gathering facts; are these blessed links?

[Matt England]

I'm new to svnmerge as per:
http://svn.haxx.se/users/archive-2006-02/0570.shtml

I'm trying to collect pertinent svnmerge info in one place--this email--and 
see if this info is valid.  An aside: does an authoritative svnmerge 
wiki/wikipage exist?

Do these references provide legitimate info?

http://www.dellroad.org/svnmerge/index
http://www.sipfoundry.org/tools/svnmerge.html

References I've received directly from Blair:

http://svn.collab.net/repos/svn/trunk/contrib/client-side/svnmerge.py
