Syntax:
  pod [ -h | -v | -p ]
  pod [-s <podlist>] [-k] [-[d|D] <delim>] -[b|i|l|m] [--] [<cmd...>]
	-h    help, output this help (the default) and exit
	-v    version, output version information/commentary and exit
	-p    pods, output the current pod list and exit

	-s    set pod list to <podlist> (delimited by ":" or " ")
	-k    keep nonextant path elements, which normally are culled

	-d    delim, set the path delimiter to be <delim> (not "@")
	-D    like -d, but also replaces ":" in %e (for *csh users)
	-f    format, set format string for path outputs.  Escapes:

	-b    bins, output the pod command (bin) search path
	-i    incs, output the pod include search path
	-l    libs, output the pod library search path
	-m    mans, output the pod manual search path
	      %p - full path
	      %t - path type (ie: 'bin', 'man', 'lib', 'inc')
	      %v - path variable (ie: PATH, MANPATH, LDPATH, INCPATH)
	      %e - pre-existing environment value of corresponding %v
	      %n - newline
	--    no more options (anything following is <cmd>)
	With <cmd>, runs a cmd with PATH, MANPATH, LDPATH, INCPATH,
	      LD_LIBRARY_PATH, and INCPATH variables, modified to
	      include elements as would be seen by -b, -l, and -m.
	Multiple path requests are output one per line,
	      each formatted as directed by -f (default "%p\n"
	pod catenates available pods (unless overriden by -s) from:
	      the PODS environment variable, if it exists
	      the /etc/pods file (or output of, if executable)
	      the auto.pod NIS map

Example for sh family:
	eval `pod \
		-f "%v=$HOME/bin:%e:/usr/games:%p%n" -b \
		-f "%v=/usr/man:/usr/local/man:%p%n" -m \
		-f "%v=/usr/lib:/usr/local/lib:%p%n" -l \
		-f "%v=/usr/include:/usr/local/include:%p%n" -i`
	LD_LIBRARY_PATH=$LDPATH	# compatibility
	export PATH MANPATH LDPATH LD_LIBRARY_PATH INCPATH
