The development versions usually reside in directories like:
  lisp-mine/package/M.Ndev/

old notes:

Please note:

For A note on the documentation, see DOCUMENTATION

About half of the pieces here are in very good condition, but about
half of them don't work yet, or have been abandoned.

How to tell?

Simple:

The "good" ones have been posted on g.e.sources 2001 or later..
Also look at the file stamps of the files..


if there is no non-alpha version and all you see are 'alpha's' or
"devs", that library has obviously never been 'released' and has most
likely been abandoned..  unless there is a REAMDE there that claims
that it works..

All others where you see a beta or a numbered non-alpha version should
work just fine..

as of today:

In particular, I heartily recommend: (arkanoid), autokey, bbdbrc,
choose, edlib, elder, filewatch, idledo, miniedit, runshell,
runshell-shortcuts, settags, shellhist, timerfunctions.

Note: subdirs.el here is NOT a library, it is just something for
me---for my .emacs..

;;;====================================================
Also, for help on any library foo, see its first 100 or so
header-lines carefully..  for nicer formatted help, download and the
file foo and type M-x foo-introduction or M-x foo-quick-start or M-x
foo-commentary.
