== Description ==

The GNU Readline library provides a set of functions for use by
applications that allow users to edit command lines as they are typed
in. Both Emacs and vi editing modes are available. The Readline
library includes additional functions to maintain a list of
previously-entered command lines, to recall and perhaps reedit those
lines, and perform csh-like history expansion on previous commands.

== Special Update/Build Instructions ==

We build readline using ncurses. Readline needs to be told to link
with libtinfo (part of ncurses), this is what the patch
0002-ltinfo.patch does.


== Patches ==

 * 0001-macports.patch: Changes to shobj.conf for OS/X, from macports:
     https://trac.macports.org/browser/trunk/dports/devel/readline/files/patch-shobj-conf.diff
 * 0002-ltinfo.patch: We build readline using ncurses, and for that it
   needs to be told to link with libtinfo (part of ncurses).
 * sigsetjmp.patch: Correctly define sigsetjmp and friends on Cygwin.
