I can easily do:


EMACS/lisp
EMACS/lisp/lots-of-files.el
EMACS/lisp/textmodes/
EMACS/lisp/progmodes
EMACS/lisp/packages
EMACS/lisp/packages/package-1
EMACS/lisp/packages/package-2
EMACS/lisp/packages/package-3


This adds a little complexity to the build part of the make file; in
return, it leaves the install part of the make file untouched. It also
requires a package.el to be extended slightly to extend the current
initialization process.

I could less easily do:

EMACS/lisp
EMACS/lisp/lots-of-files.el
EMACS/lisp/textmodes/package-1
EMACS/lisp/progmodes/package-2
EMACS/lisp/emacs-lisp/package-3


This requires updating the current build process to exclude multiple
directories, and the package.el section of my branch to include multiple
directories. I also dislike this, because I think it mixes up files of
different kinds in the tree (that is files which are in place in the
Emacs git repo, and those which are not).

Finally, it would no doubt be possible to do:

EMACS/lisp
EMACS/lisp/textmodes/package-1a.el
EMACS/lisp/textmodes/package-1b.el
EMACS/lisp/textmodes/package-1c.el
EMACS/lisp/progmodes/package-2.el
EMACS/lisp/emacs-lisp/package-3.el

This would need no use at all of package.el, but would require something
to get the files into the right place and should leave the build
otherwise untouched. Superficially, this is the simplest. However, in
practice, I think it's the most complex and least convienient, for
reasons I have outlined and documented.
