=head1 DESCRIPTION
-This is a module used for templating Excel files. Its genesis came from the
-need to use the same datastructure as HTML::Template, but provide Excel files
-instead. The existing modules don't do the trick, as they require replication
-of logic that's already been done within HTML::Template.
+This is a module used for templating Excel files. Its genesis came from the need to use the same datastructure as L<HTML::Template>, but provide Excel files instead. The existing modules don't do the trick, as they require replication of logic that's already been done within L<HTML::Template>.
=head1 MOTIVATION
-I do a lot of Perl/CGI for reporting purposes. In nearly every place I've been,
-I've been asked for HTML, PDF, and Excel. HTML::Template provides the first, and
-PDF::Template does the second pretty well. But, generating Excel was the
-sticking point. I already had the data structure for the other templating
-modules, but I just didn't have an easy mechanism to get that data structure
-into an XLS file.

This will use L<Unicode::String> to represent strings instead of Perl's internal string handling. You must already have L<Unicode::String> installed on your system.
-The USE_UNICODE parameter will be ignored if you are using Perl 5.8 or higher as
-Perl's internal string handling is unicode-aware.

-NOTE: Certain older versions of L<OLE::Storage_Lite> and mod_perl clash for some

-problem.

This method actually parses the template file. It can either be called separately or through the new() call. It will die() if it runs into a situation it cannot handle.
-If a filename is passed in (vs. a filehandle), the directory name will be passed in to XML::Parser as the I<Base> parameter. This will allow for XML directives to work as expected.
