The easiest way to get it right is to check a separate copy of the boost cvs
tree out, and make the fix there. This command line will bring down only
code-related materials and save you from making another copy of peoples'
pictures and auxiliary documentation:

  mkdir release_<version>
  cd release_<version>
  cvs -d :ext:<username> \
    checkout -r<version>_branch boost/libs boost/boost boost/tools

[This assumes that we have a branch tag called <version>_branch for all
release candidates of the official Version_<version>. In other words, all
release candidates for Version_1_3_2 will be on the branch called

If you just want to get everything, just list "boost" instead of
boost/libs,... etc.

Make the fixes in this new cvs tree

Test your fixes. Keep in mind that if you're using Jam
with -sALL_LOCATE_TARGET=... that you may need to choose a different target
location or clean before you build, since there may be old objects hanging

Commit your fixes. In a directory no lower than the highest directory where
you made a fix:

    cvs commit

CVS will bring up a window with a list of the files you've modified/added.
Save this list somewhere that you'll be able to get it back later. Let's
call that <mod-list>

cd back to your regular working tree.

When you're ready to bring in all the bugfixes in from the release
candidate, first make sure all of your current changes are checked in. Then
go to the place in your working CVS tree where you did the commit in the
release candidate tree and:

    cvs update -j<version>_branch <mod-list>

All of your fixes will be merged into your current working copy. When you
commit, they will go into whatever branch you're on, or the main trunk.
