HTML/Processor version 0.0.2
============================

    HTML::Processor HTML Template Processor
    

DESCRIPTION

Processor.pm is primarily an HTML template processing utility.
It is designed to remove html from perl 
scripts without putting too much Perl into the html. 
The tag syntax (configurable) is somewhat verbose in order to 
not scare off html coders, while retaining some Perl logic and 
functionality. The Perl interface is OO for flexibility and 
clarity and has a fairly basic set of methods. While its not 
as heavy duty as some of the other Template modules, it 
occupies a firm middle ground with all the essential data
replacement funtions.

  Functionality:
    - File includes
    - Optional content
    - If/Else blocks
    - Variable substitution
    - Loops (nested recursively)
      - Loop Optional content
      - Loop If/else blocks
    - Data sorting (columns)
    - Debugging, Perl and Object data
    
    
DOCUMENTATION

All documentation, with examples, is in Processor.pm, additionally in Processor.html
which was generated via pod2html from Processor.pm
