(synopsis "Edit command lines while typing, with history support")
(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.
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.")
