I've read the manual, thanks.  I didn't say exactly *how* I can make
one commit across multiple projects.  With something like emacs
svn-mode you diff/tag with a few keystrokes and you make one commit
across multiple projects.  Or you can simply commit like this:

  svn commit *

assuming everything that '*' matches is under version control, which
it is when you do out-of-source builds, if not you can

  svn commit project1 project2 project3

There are myriad convenient ways to work with a checkout full of
externals.
