NAME

       Astro::FITS::Header::AST - Manipulates FITS headers from an AST object

SYNOPSIS

	 use Astro::FITS::Header::AST;

	 $header = new Astro::FITS::Header::AST( FrameSet => $wcsinfo );
	 $header = new Astro::FITS::Header::AST( FrameSet => $wcsinfo,
						 Encoding => 'FITS-IRAF' );

	 $header = new Astro::FITS::Header::AST( Cards => @cards );

DESCRIPTION

       This module makes use of the Starlink::AST module to read the FITS HDU from an AST FrameSet object.

       It stores information about a FITS header block in an object. Takes an hash as an argument, with an array reference pointing to an
       Starlink::AST FramSet object.

REVISION

       $Id$

METHODS

       configure
	   Reads a FITS header from a Starlink::AST FrameSet object

	     $header->configure( FrameSet => $wcsinfo );

	   Base class initialisation also works:

	     $header->configure( Cards => @cards );

	   Accepts a reference to an Starlink::AST FrameSet object.

	   If a specific encoding is required, this can be specified using the Encoding argument. Default is FITS-WCS if no Encoding is given.
	   Note that not all framesets can be encoded using FITS-WCS.

	     $header->configure( FrameSet => $wcsinfo, Encoding => "Native" );

	   If Encoding is specified but undefined, the default will be decided by AST.

NAME

       Makefile::AST - AST for (GNU) makefiles

DESCRIPTION

       The structure of this (GNU) makefile AST is designed based on GNU make's data base listing output produced by "--print-data-base".

       This AST library provides the following classes:

       Makefile::AST
	   The primary class for ASTs. Provides interface for node adding and querying, such as "add_implicit_rule", "apply_implicit_rules",
	   "add_explicit_rule", "apply_explicit_rules", "add_var", "add_auto_var", "get_var", as well as lots of other utility functions, like
	   method "eval_var_value" for computing the ultimate values of makefile variables, method "enter_pad" and "leave_pad" for local
	   variable's scoping pad.

       Makefile::AST::Rule::Base
	   This is the base class for the rule nodes in the AST. It has properties like "normal_prereqs", "order_prereqs", "commands", and
	   "colon".

       Makefile::AST::Rule
	   This class represents the de-sugared form of simple rules and implicite rules after application. It inherits from
	   Makefile::AST::Rule::Base, and adds new properties "target" and "other_targets".

       Makefile::AST::Rule::Implicit
	   This class represents the implicit rule nodes in the AST. It inherits from Makefile::AST::Rule::Base, and adds new properties
	   "targets", "match_anything", and "is_terminal".

       Makefile::AST::StemMatch
	   This class encapsulates the file pattern matching (file names containing "%") and stem substitution algorithms.

       Makefile::AST::Variable
	   It represents the makefile variable nodes in the AST, including "name", "value", "flavor", and "origin".

       Makefile::AST::Command
	   Used to encapsulate information regarding makefile rule commands (e.g. command body, command modifiers "@", "-", "+", and etc.) as a
	   whole.

LIMITATIONS AND TODO

       Adding support for other flavors' makes into this AST library should make a huge amount of sense. The most interesting candiate is
       Microsoft's NMAKE.
