hg tools flag day email

From Genunix

The flag day (or heads-up) email needs to cover at least these topics:

• changes that TeamWare users will see, if any
  • findunref changes (exception list)
  • cstyle/jstyle pickier?
  • changes to cddlchk CLI (no -M, --help, or --version)
  • anything else? (review bugs listed in the webrev for possible topics)
• information for Mercurial users
  • enabling Cadmium
  • getting Mercurial (1.0, i.e., snv_88 or later)
  • pointer to the 2007-8-13 KTD
  • pointers to documentation (has crucial information like the fact that the closed tree is a separate repo)
  • known issues
• general changes
  • CAS scripts and #ident (don't depend on SCCS keywords)
