<simpara>
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 meant to be run from a shell.

The home page of the GNU Readline project is
<ulink url="&url.readline;">&url.readline;</ulink>. It's maintained
by Chet Ramey, who's also the author of Bash.

This function returns a single string from the user. You may specify
a string with which to prompt the user. The line returned has the
ending newline removed. You must add this line to the history yourself
using <function>readline_add_history</function>.

This function registers a completion function. You must supply the name of
an existing function which accepts a partial command line and returns an array
of possible matches. This is the same kind of functionality you'd get if you
hit your tab key while using Bash.

<para>
If called with no parameters, this function returns an array of values
for all the setting readline uses. The elements will will be indexed
by the following values: done, end, erase_empty_line, library_version,
line_buffer, mark, pending_input, point, prompt, readline_name, and
terminal_name.

<para>
If called with one parameter, the value of that setting is returned.
If called with two parameters, the setting will be changed to the given
value.
