- changed the way POD is generated such that the dashed

Browse Source 
line appears at the bottom instead of the top.  The
  indentation semantics of POD make the first item in
  the (=over,=back) block look weird the other way.
- implemented a way to encode example usage into usage.h
  One would define a macro called "${applet}_example_usage"
  which would expand to the example text.
- The example usage is considered optional, but trivial and
  full usage are not.

  Here's an example using chown.

---- before

#define chown_trivial_usage \
	"[OPTION]...  OWNER[<.|:>[GROUP] FILE..."
#define chown_full_usage \
	"Change the owner and/or group of each FILE to OWNER and/or GROUP.\n" \
	"\nOptions:\n" \
	"\t-R\tChanges files and directories recursively."
#define chown_example_usage \
	"\t$ ls -l /tmp/foo\n" \
	"\t-r--r--r--    1 andersen andersen        0 Apr 12 18:25 /tmp/foo\n" \
	"\t$ chown root /tmp/foo\n" \
	"\t$ ls -l /tmp/foo\n" \
	"\t-r--r--r--    1 root     andersen        0 Apr 12 18:25 /tmp/foo\n" \
	"\t$ chown root.root /tmp/foo\n" \
	"\tls -l /tmp/foo\n" \
	"\t-r--r--r--    1 root     root            0 Apr 12 18:25 /tmp/foo\n"

---- after

=item I<chown>

chown [OPTION]...  OWNER[<.|:>[GROUP] FILE...

Change the owner and/or group of each FILE to OWNER and/or GROUP.

Options:

	-R	Changes files and directories recursively.

Example:

	$ ls -l /tmp/foo
	-r--r--r--    1 andersen andersen        0 Apr 12 18:25 /tmp/foo
	$ chown root /tmp/foo
	$ ls -l /tmp/foo
	-r--r--r--    1 root     andersen        0 Apr 12 18:25 /tmp/foo
	$ chown root.root /tmp/foo
	ls -l /tmp/foo
	-r--r--r--    1 root     root            0 Apr 12 18:25 /tmp/foo
