	<para>
	BusyBox combines tiny versions of many common UNIX utilities into a single
	small executable. It provides minimalist replacements for most of the
	utilities you usually find in fileutils, shellutils, findutils, textutils,
	grep, gzip, tar, etc. BusyBox provides a fairly complete POSIX environment
	for any small or embedded system. The utilities in BusyBox generally have
	fewer options than their full-featured GNU cousins; however, the options
	that are included provide the expected functionality and behave very much
	like their GNU counterparts. 
	</para>

	<para>
	BusyBox has been written with size-optimization and limited resources in
	mind. It is also extremely modular so you can easily include or exclude
	commands (or features) at compile time. This makes it easy to customize
	your embedded systems. To create a working system, just add a kernel, a
	shell (such as ash), and an editor (such as elvis-tiny or ae).

	    <title>Invoking BusyBox</title>

	    <para>
	    When you create a link to BusyBox for the function you wish to use, when
	    BusyBox is called using that link it will behave as if the command itself
	    has been invoked.
	    </para>

	    <para>
	    For example, entering
	    </para>

	    <para>
	    <screen>
		    ln -s ./BusyBox ls
		    ./ls
	    </screen>
	    </para>

	    <para>
	    will cause BusyBox to behave as 'ls' (if the 'ls' command has been compiled
	    into BusyBox). 
	    </para>

	    <para>
	    You can also invoke BusyBox by issuing the command as an argument on the
	    command line. For example, entering
	    </para>

	    <para>
	    <screen>
		    ./BusyBox ls
	    </screen>
	    </para>

		lexicographical.  Pattern matches return the string matched between
		\( and \) or null; if \( and \) are not used, they return the number
		of characters matched or 0.

  <chapter id="LIBC-NSS">
    <title>LIBC NSS</title>

	<para>
	GNU Libc uses the Name Service Switch (NSS) to configure the
	behavior of the C library for the local environment, and to
	configure how it reads system data, such as passwords and group
	information. BusyBox has made it Policy that it will never use
	NSS, and will never use libc calls that make use of NSS. This
	allows you to run an embedded system without the need for
	installing an /etc/nsswitch.conf file and without /lib/libnss_*
	libraries installed.
	</para>

	<para>
	If you are using a system that is using a remote LDAP server for
	authentication via GNU libc NSS, and you want to use BusyBox,
	then you will need to adjust the BusyBox source. Chances are
	though, that if you have enough space to install of that stuff
	on your system, then you probably want the full GNU utilities.
