Blis is a CGI based Content Management System, written in awk, light and very fast. It uses plain text files written in wiki-style syntax as page sources, parses them, applies a selectable template and presents the results to the reader as web content.
A verification library accompanied by a simple tool for verification of credit-cards, social security-numbers and other mod(10) and similar checksums in a standard shell-environment from the command-line or as a function. No compilation required.
