       PDL::Doc::Perldl - commands for accessing PDL doc database from 'perldl' shell

       This module provides a simple set of functions to access the PDL documentation of data-
       base, for use from the perldl shell and the pdldoc command-line program.

       Currently, multiple matches are not handled very well.

	use PDL::Doc::Perldl; # Load all documenation functions


       Regex search PDL documentation database

	apropos 'text'

	perldl> apropos 'pic'
	rpic		Read images in many formats with automatic format detection.
	rpiccan 	Test which image formats can be read/written
	wmpeg		Write an image sequence ((x,y,n) piddle) as an MPEG animation.
	wpic		Write images in many formats with automatic format selection.
	wpiccan 	Test which image formats can be read/written

       To find all the manuals that come with PDL, try

	 apropos 'manual:'

       and to get quick info about PDL modules say

	 apropos 'module:'

       You get more detailed info about a PDL function/module/manual with the "help" function


       Prints usage information for a PDL function

	Usage: usage 'func'

	  perldl> usage 'inner'

	  inner 	  inner prodcuct over one dimension
			  (Module PDL::Primitive)

	  Signature: inner(a(n); b(n); [o]c(); )


       prints signature of PDL function

	sig 'func'

       The signature is the normal dimensionality of the functions arguments. Calling with dif-
       ferent dimensions causes 'threading' - see "PDL::PP" for more details.

	 perldl> sig 'outer'
	   Signature: outer(a(n); b(m); [o]c(n,m); )


       print documentation about a PDL function or module or show a PDL manual

       In the case of multiple matches, the first command found is printed out, and the remaining
       commands listed, along with the names of their modules.

	Usage: help 'func'

	perldl> help 'PDL::Slices'   # show the docs in the PDL::Slices module
	perldl> help 'PDL::Intro'    # show the PDL::Intro manual
	perldl> help 'slice'	     # show docs on the 'slice' function


       provides information on the bad-value support of a function

       And has a horrible name.

	badinfo 'func'
