I simply got the 0.9.4 version from:

     http://www.selenic.com/mercurial/wiki/index.cgi/BinaryPackages

and then cloned hgforest from the source, copied the .py file right into 
the c:/Mercurial directory and pointed my .hgrc file to it.  No 
"batteriesrequired" distribution.

What *WASN'T* immediately obvious to me is that there was no hgmerge 
file in these distributions.  It makes some sense, given that the 
standard hgmerge file is a UNIX sh script, but since I'm using MKS...

At least on my system, this file *HAD* to be called "hgmerge.sh".  If it 
was "hgmerge", it would expect a DOS batch file, and thus wouldn't run. 
  So I simply copied over the UNIX hgmerge into:

     c:/Mercurial/hgmerge.sh

tweaked the PATH variable to reflect the various locations of my diff 
programs, and let it go.

I'm sure there will be more info on this soon, but something else you 
should be aware of working on windows:  the "CR-LF" issue.  OpenJDK has 
standardized on the Unix end-of-line ("LF") style.  I know some windows 
editors can be set to only write a "LF", but most editors insert the 
"CR", which means you will need to strip these before the new changeset 
checker will accept them.

MKS has flip(1), others have dos2unix(1)...

The reason for this requirement is because if a Unix changeset follows a 
Windows changeset, Mercurial will happily store two complete versions of 
the file, rather than just the deltas.
