+Common-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.
