This new backend allows gnus to handle arbitrary sets of messages
spanning multiple groups, even when these groups are from different
backends and different servers. All gnus glue is removed from
nnir (leaving only the backend search functions) and gnus
search-related processing is done through nnselect. In appropriate
places 'nnir' has been replaced by 'nnselect' or 'search'.

This directory contains source code for the parts of Emacs that are
written in Emacs Lisp. *.el files are Emacs Lisp source, and the
corresponding *.elc files are byte-compiled versions. Byte-compiled
files are architecture-independent.
The term subdirectory contains Lisp files that customize Emacs for
certain terminal types. When Emacs starts, it checks the TERM
environment variable to get the terminal type and loads
'term/${TERM}.el' if it exists.
The other subdirectories hold Lisp packages grouped by their general
purpose.
