The <function>readline</function> functions implement an interface
to the GNU Readline library. These are functions that provide
editable command lines. An example being the way Bash allows you
to use the arrow keys to insert characters or scroll through
command history. Because of the interactive nature of this
library, it will be of little use for writing Web applications,
but may be useful when writing scripts used from a
<link linkend="features.commandline">command line</link>.

<para>
To use the readline functions, you need to install libreadline. You can
find libreadline on the home page of the GNU Readline project, at
<ulink url="&url.readline;">&url.readline;</ulink>.
It's maintained by Chet Ramey, who's also the author of Bash.

<para>
You can also use these functions with the libedit library, a non-GPL
replacement for the readline library. The libedit library is BSD
licensed and available for download from
<ulink url="&url.libedit;">&url.libedit;</ulink>.
