.SH NAME
HTML::Template::Pro \- Perl/XS module to use HTML Templates from CGI scripts
.SH SYNOPSIS
.IX Header "SYNOPSIS"
It is moved out and split.
.PP
See "SYNOPSIS" in HTML::Template::SYNTAX for introduction 
to HTML::Template and syntax of template files.
.PP
See "SYNOPSIS" in HTML::Template::PerlInterface for perl interface
of HTML::Template, HTML::Template::Expr and HTML::Template::Pro.
.SH DESCRIPTION
.IX Header "DESCRIPTION"
Original HTML::Template is written by Sam Tregar, sam@tregar.com
with contributions of many people mentioned there.
Their efforts caused HTML::Template to be mature html tempate engine
which separate perl code and html design.
Yet powerful, HTML::Template is slow, especially if mod_perl isn't 
available or in case of disk usage and memory limitations.
.PP
HTML::Template::Pro is a fast lightweight C/Perl+XS reimplementation
of HTML::Template (as of 2.9) and HTML::Template::Expr (as of 0.0.7). 
It is not intended to be a complete replacement, 
but to be a fast implementation of HTML::Template if you don't need 
querying, the extended facility of HTML::Template.
Designed for heavy upload, resource limitations, abcence of mod_perl.
.PP
HTML::Template::Pro has complete support of filters and HTML::Template::Expr's 
tag EXPR="<expression>", including user-defined functions and
construction <TMPL_INCLUDE EXPR="...">.
.PP
HTML::Template work cycle uses 2 steps. First, it loads and parse template.
Then it accepts \fBparam()\fR calls until you call \fBoutput()\fR.
\&\fBoutput()\fR is its second phase where it produces a page from the parsed tree
of template, obtained in the 1st step.
.PP
HTML::Template::Pro loads, parse and outputs template on fly, 
when you call \f(CW$tmpl\fR\->\fBoutput()\fR, in one pass. The corresponding code is 
written in C and glued to Perl using Perl+XS. As a result,
comparing to HTML::Template in ordinary calls, it runs 
10\-25 times faster. Comparing to HTML::Template with all caching enabled
under mod_perl, it still 1\-3 times faster. At that HTML::Template caching 
requires considerable amount of memory (per process, shareable, or on disk) 
to be permanently filled with parsed trees, whereas HTML::Template::Pro 
don't consumes memory for caches and use \fBmmap()\fR for reading templates on disk.
.PP
Introduction to HTML::Template and syntax of template files is described 
in HTML::Template::SYNTAX.
Perl interface of HTML::Template and HTML::Template::Pro is described 
in HTML::Template::PerlInterface.
