Here is a script to extract changesets with Mercurial (Distributed
SCM) and cvs20hg (CVS to Mercurial converter).

One problem of this script is extracted changeset "emacs-trunk-09"
contains incorrect difference for "$Id$" since cvs20hg seems to ignore
sticky flag for keyword expansion.

But it can be fixed to edit the changeset by hand because its format
is usual unified diff.
