A Perl module (two,
to be precise) that allows the use of Perl in templates like HTML.

It is very similar
to JSP, PHP,
ASP, and other template languages.
In fact, the entire idea is assembled from these languages. However, there
are few notable differences.

• It embeds Perl
  - our kind of language, not java, not VB!
  
• It is extremely
  simple - there are only 4 different tags, no need for a 100-page
  manual.
  
• It is open
  and compatible - the core of PEE is the parser, which compiles
  the template into ordinary perl code. It does not get in your
  usual way of perl programming, since it does not do more than assembling
  layout code with logic-handling code. It does not even require mod_perl,
  although you may use it.
  
• It is extensible
  - because everything is open, you may build a caching mechanism easily,
  or add additional tags.
