=head1 SYNOPSIS

	package foo;
	use Meta::Tool::Aspell qw();
	my($object)=Meta::Tool::Aspell->new();
	my($result)=$object->method();

=head1 DESCRIPTION

This module hides the complexity of running aspell on SGML documents
from you.

	TEST($)

=head1 FUNCTION DOCUMENTATION

=over 4

=item B<BEGIN()>

Bootstrap method to locate your aspell executable.

=item B<checksgml($)>

This method will check an sgml source file for spell correctness.
It returns a boolean specifiying whether it is correct or not.
There are several problems in aspell:
0. If you dont want it to run interactivly you have to use the --list
	(-l) flag but when using this option you cannot use
	aspell to check a file but only stdin.
1. Aspell's exit code does not imply if the document was correct or
	not. In order to do that you have to check that the output
	list is empty.
At the end, this module uses my Unique module to produce a list of different
words which were not spelled correctly.

Another problem is that Aspell that not recurse into included docbook documents.

=item B<checkhtml($)>

This method will check an HTML file for syntax errors.
Currently it just calls the SGML version because all
our HTML documents are SGML compliant.

=item B<checktxt($)>

This method will check a regular text file.
Currently it is unimplemented and just returns true.

=item B<TEST($)>

Test suite for this module.
