ClearOS is an integrated network server gateway solution for small and distributed organizations. The software provides all the necessary server tools to run an organization including email, anti-virus, anti-spam, file sharing, groupware, VPN, firewall, intrusion detection/prevention, content filtering, bandwidth management, multi-WAN, and more. You can think of it as a next generation small business server. Through the intuitive Web-based management console, an administrator can configure the server software along with integrated cloud-based services.
Minimac is a minimalist, general purpose text macro processor. Its simplicity should make it particularly well suited as a front end preprocessor for little language compilers. It is meant to be simpler to use than m4. It uses an explicit argument stack, and user functions are defined by concatenation (similar to the Forth language). Macro expansion is delayed to the last possible moment. The software is currently in alpha release.
LEPL is a recursive descent parser library written in Python. It is based on parser combinator libraries popular in functional programming, but also exploits Python language features. Operators provide a friendly syntax, and the consistent use of generators supports full backtracking and resource management. Backtracking implies that a wide variety of grammars are supported; appropriate memoisation ensures that even left-recursive grammars terminate.
GLD-fork is a fork of the GLD program by Salim Gasmi. The fork has been made because the original project has been dead for many years, and some new featured were needed. GLD-fork, as with the original GLD, adds greylisting functionality to the Postfix mail server. Greylisting is a fairly resource friendly anti-spam technique. GLD-fork can easily be combined with other (more resource consuming) tools to build anti-spam protection.
