Generally looks good.
wx2hg.1:
24 date should be updated to today.
126-132 there should be some discussion on how to use -r with nested
repositories. Maybe something like
If you are making any changes in a nested repository (e.g.,
usr/closed), hg_rev must be the same in the main and nested
repository. If you have write access to the parent
repositories, you can do this by giving them the same tag.
Otherwise, you will need to use a revision that is already
tagged, such as a biweekly snapshot revision.
wx2hg.sh:
86 this should be wrapped with "set -x"/"set +x" for consistency
with other hg operations.
254-257 this assumes that any nesting is only one repo deep (e.g., there
isn't another repo under usr/closed). That's a reasonable
assumption, but it'd be nice to have a comment mentioning it.
