Libreadline

The 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.

The history facilites are also placed into a separate library, the
History library, as part of the build process.  The History library
may be used without Readline in applications which desire its
capabilities.

Both clib2 and newlib compiles are included. The modified sources are in the
archive, too.

The Readline library is free software, distributed under the terms of
the [GNU] General Public License, version 2.  For more information, see
