Just converted busybox.pod to busybox.sgml using the Pod::DocBook Perl module.
The resulting file needs some massaging and once it gets presentable, I'll
edit the Makefile to use the SGML file as the "authoritative" file; the plan
here is to generate other file formats from the SGML.

+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).

+<!-- Bogus hack to ensure that each sect has a paragraph in it -->
+<para>
+</para>
+
+
+<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>

+ WARNING: This field has a non-traditional meaning for BusyBox init!
+ The id field is used by BusyBox init to specify the controlling tty for

+ appended to "/dev/" and used as-is. There is no need for this field to
+ be unique, although if it isn't you may have strange results. If this
+ field is left blank, it is completely ignored. Also note that if
+ BusyBox detects that a serial console is in use, then all entries
+ containing non-empty id fields will _not_ be run. BusyBox init does
+ nothing with utmp. We don't need no stinkin' utmp.

+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 and 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 and /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.
