gnus: Directory Groups
6.6.1 Directory Groups
----------------------
If you have a directory that has lots of articles in separate files in
it, you might treat it as a newsgroup. The files have to have numerical
names, of course.
This might be an opportune moment to mention ‘ange-ftp’ (and its
successor ‘efs’), that most wonderful of all wonderful Emacs packages.
When I wrote ‘nndir’, I didn’t think much about it—a back end to read
directories. Big deal.
‘ange-ftp’ changes that picture dramatically. For instance, if you
enter the ‘ange-ftp’ file name ‘/ftp.hpc.uh.edu:/pub/emacs/ding-list/’
as the directory name, ‘ange-ftp’ or ‘efs’ will actually allow you to
read this directory over at ‘sina’ as a newsgroup. Distributed news
ahoy!
‘nndir’ will use NOV files if they are present.
‘nndir’ is a “read-only” back end—you can’t delete or expire articles
with this method. You can use ‘nnmh’ or ‘nnml’ for whatever you use
‘nndir’ for, so you could switch to any of those methods if you feel the
need to have a non-read-only ‘nndir’.
