       CGI::FormBuilder::Source	- Source adapters for FormBuilder

	   # Define a source adapter

	   package CGI::FormBuilder::Source::Whatever;

	   sub new {
	       my $self	 = shift;
	       my $class = ref($self) || $self;
	       my %opt	 = @_;
	       return bless \%opt, $class;

	   sub parse {
	       my $self	= shift;
	       my $file	= shift	|| $self->{source};

	       # open the file and parse it, or	whatever
	       my %formopt;
	       open(F, "<$file") || die	"Can't read $file: $!";
	       while (<F>) {
		   # ... do stuff to the line ...
		   $formopt{$fb_option}	= $fb_value;

	       # return	hash of	$form options
	       return wantarray	? %formopt : \%formopt;

       This documentation describes the	usage of FormBuilder sources, as well
       as how to write your own	source adapter.

       An external source is invoked by	using the "source" option to the top-
       level "new()" method:

	   my $form = CGI::FormBuilder->new(
			   source => 'source_file.conf'

       This example points to a	filename that contains a file following	the
       "CGI::FormBuilder::Source::File"	layout.	Like with the "template"
       option, you can also specify "source" as	a reference to a hash,
       allowing	you to use other source	adapters:

	   my $form = CGI::FormBuilder->new(
			   fields => \@fields,
			   source => {
			       type => 'File',
			       source => '/path/to/source.conf',

       The "type" option specifies the name of the source adapter. Currently
       accepted	types are:

	   File	 -  CGI::FormBuilder::Source::File

       In addition to one of these types, you can also specify a complete
       package name, in	which case that	module will be autoloaded and its
       "new()" and "parse()" routines used. For	example:

	   my $form = CGI::FormBuilder->new(
			   fields => \@fields,
			   source => {
			       type => 'My::Source::Module',
			       somefile	=> '/path/to/source.conf',

       All other options besides "type"	are passed to the constructor for that
       source module verbatim, so it's up to you and/or	the source module on
       how these additional options should be handled.
