Lets say I have detarred a copy of pkgsrc.tar.gz
which is now obsolete.  Suppose I only install a
few packages, or that I know only a few of my
installed packages are out of date.

Is there a way from within print/tex (or something)
to do a "make blah" which will ftp just the files
in that subdirectory (eg, pkg, files, Makefile,
patches, etc).  I need ftp, not cvs.
