+> HTML::Template allows the use of `<!-- TMPL_SOMETHING ... -->`

+> <http://search.cpan.org/~samtregar/HTML-Template-2.6/Template.pm#NOTES>
+> for details. I used this PERL regexp to convert my own templates:

+> s{<\s*(/?TMPL_[A-Z]+)((\s+\w+(=(['"]?)\w+\5)?)+)?\s*/?>}{<!-- $1$2 -->}gi;

+> (Quoting it properly to use from the shell command-line is
+> nightmarish, write a script with it.)
