[TOOL] CVS add directories recursively

First, add all the directories, but not any named "CVS":

find . -type d \! -name CVS -exec cvs add '{}' \;

Then add all the files, excluding anything in a CVS directory:

find . \( -type d -name CVS -prune \) -o \( -type f -exec cvs add '{}' \; \)
find . -type f -print0| xargs -0 cvs add
