=head1 NAME
-TmplTokenizer.pm - Simple-minded tokenizer class for HTML::Template .tmpl files
+TmplTokenizer.pm - Simple-minded wrapper class for TTParser
=head1 DESCRIPTION
-Because .tmpl files contains HTML::Template directives
-that tend to confuse real parsers (e.g., HTML::Parse),
-it might be better to create a customized scanner
-to scan the template files for tokens.
-This module is a simple-minded attempt at such a scanner.
+A wrapper for the functionality found in TTParser to allow an easier transition to Template Toolkit

+
+The character % is followed by zero or more of the following flags:
+
+=over
+
+=item #
+
+The value comes from HTML <INPUT> elements.
+This abuse of the flag character is somewhat reasonable,
+since TMPL_VAR and INPUT are both variables, but of different kinds.

+
+=head2 The field width and precision
+
+An optional 0.0 can be specified for %s to specify
+that the <TMPL_VAR> should be suppressed.
+
+=head2 The conversion specifier
+
+=over
+
+=item p
+
+Specifies any input field that is neither text nor hidden
+(which currently mean radio buttons).
+The p conversion specifier is chosen because this does not
+evoke any certain sensible data type.
+
+=item S
+
+Specifies a text input field (<INPUT TYPE=TEXT>).
+This use of the S conversion specifier is somewhat reasonable,
+since text input fields contain values of undeterminable type,
+which can be treated as strings.
+
+=item s
+
+Specifies a <TMPL_VAR>.
+This use of the o conversion specifier is somewhat reasonable,
+since <TMPL_VAR> denotes values of undeterminable type, which
+can be treated as strings.

+
+There is no code to save the tag name anywhere in the scanned token.
+
+The use of <AI<i>> to stand for the I<i>th anchor
+is not very well thought out.
+Some abuse of c-format specifies might have been more appropriate.
