# svnupdate -- update all my SVN projects (or the current directory)
#
# SUMMARY: If you give this no parameters,
#          it looks first in the current directory, if that's a SVN directory,
#          then it acts like svn update
#          If there are no arguments,
#          and if the current directory isn't a SVN directory, then
#          it updates all of the immediate subdirectories of . that are SVN
#          directories.
#          If you give it arguments, it updates all of the given directories.
