libterm-readline-gnu-perl 1.17a-2 (amd64 binary) in ubuntu jaunty

 This is an implementation of a Perl interface to the GNU Readline
 Library. This module gives you input line editing, input history
 management, word completion, and other similar facilities. This module
 gives you access to almost all variables and functions documented in
 the GNU ReadLine/History Library. This means you can write your custom
 editing function, your custom completion function, and so on with Perl.
 You may find it useful for prototyping before programming with C.
