libhtml-mason-perl - 1:1.58-1 main

Mason allows web pages and sites to be constructed from shared,
reusable building blocks called components. Components contain a mix
of Perl and HTML, and can call each other and pass values back and
forth like subroutines. Components increase modularity and eliminate
repetitive work: common design elements (headers, footers, menus,
logos) can be extracted into their own components where they need be
changed only once to affect the whole site.
.
Other Mason features include a graphical site previewing utility, an
HTML/data caching model, and the ability to walk through requests with
the Perl debugger.
