NAME

       PDL::Core::Dev - PDL development module

DESCRIPTION

       This module encapsulates most of the stuff useful for PDL development and is often used from within Makefile.PL's.

SYNOPSIS

	  use PDL::Core::Dev;

FUNCTIONS

   isbigendian
       Is the machine big or little endian?

	 print "Your machins is big endian.
" if isbigendian();

       returns 1 if the machine is big endian, 0 if little endian, or dies if neither.	It uses the "byteorder" element of perl's %Config array.

	  my $retval = isbigendian();

   trylink
       a perl configure clone

	 if (trylink 'libGL', '', 'char glBegin(); glBegin();', '-lGL') {
	   $libs = '-lGLU -lGL';
	   $have_GL = 1;
	 } else {
	   $have_GL = 0;
	 }
	 $maybe =
	   trylink 'libwhatever', $inc, $body, $libs, $cflags,
	       {MakeMaker=>1, Hide=>0, Clean=>1};

       Try to link some C-code making up the body of a function with a given set of library specifiers

       return 1 if successful, 0 otherwise

	  trylink $infomsg, $include, $progbody, $libs [,$cflags,{OPTIONS}];

       Takes 4 + 2 optional arguments.

       o    an informational message to print (can be empty)

       o    any commands to be included at the top of the generated C program (typically something like "#include "mylib.h"")

       o    the body of the program (in function main)

       o    library flags to use for linking. Preprocessing by MakeMaker should be performed as needed (see options and example).

       o    compilation flags. For example, something like "-I/usr/local/lib".	Optional argument. Empty if omitted.

       o    OPTIONS

	    MakeMaker
		Preprocess library strings in the way MakeMaker does things. This is advisable to ensure that your code will actually work after
		the link specs have been processed by MakeMaker.

	    Hide
		Controls if linking output etc is hidden from the user or not.	On by default except within the build of the PDL distribution
		where the config value set in perldl.conf prevails.

	    Clean
		Remove temporary files. Enabled by default. You might want to switch it off during debugging.

NAME

       PDL::Exporter - PDL export control

DESCRIPTION

       Implements the standard conventions for import of PDL modules in to the namespace

       Hopefully will be extended to allow fine control of which namespace is used.

SYNOPSIS

       use PDL::Exporter;

	use PDL::MyModule;	 # Import default function list ':Func'
	use PDL::MyModule '';	 # Import nothing (OO)
	use PDL::MyModule '...'; # Same behaviour as Exporter

SUMMARY

       "PDL::Exporter" is a drop-in replacement for the Exporter module. It confers the standard PDL export conventions to your module.  Usage is
       fairly straightforward and best illustrated by an example. The following shows typical usage near the top of a simple PDL module:

	  package PDL::MyMod;

	  use strict;

	  # For Perl 5.6:
	  use vars qw($VERSION @ISA @EXPORT @EXPORT_OK %EXPORT_TAGS);
	  # For more modern Perls:
	  our ($VERSION, @ISA, @EXPORT, @EXPORT_OK, %EXPORT_TAGS);

	  require PDL::Exporter;

	  @ISA = qw(PDL::Exporter);
	  @EXPORT_OK = qw(inc myfunc); # these will be exported by default
	  %EXPORT_TAGS = (Func=>[@EXPORT_OK],
			  Internal => [qw/internfunc1 internfunc2/],
			 );

	   # ... body of your module

	  1; # end of simple module
