5x9 and 5x10 are two X11 fonts intended for use with xterm or other programs requiring readable small fonts. At only 5 pixels wide, they are particularly well suited to small laptop screens, allowing two 80 column windows side by side on an 800x600 screen (albeit with no room for window frames), or three windows across with room to spare on a 1280x1024 screen. The fonts implement VT100 line-drawing characters. Bolding is not directly supported; xterm does adequate bolding by duplicating pixels.
deawk is a very simple double-entry bookkeeping system designed for self-employed people. It uses three (text) data files: transactions, a chart of accounts, and an optional vehicle log. Reports are generated by running bash scripts which run awk. deawk currently does not support depreciation of capital assets.
libmawk is a fork of mawk 1.3.3 restructured for embedding. It allows you to embed awk interpreters in any application written in C or in a language that can interface C libraries. This allows the application to have plugins, configuration, run control, and AI written in awk. It extends the original feature set of mawk with modularity (C-style include), save/load of compiled bytecode, function calling by name-in-string (substitute for pointers/references), and accounting and limiting of memory and CPU use. While awk as a language does not offer OOP and complex data structures, it is still reasonably powerful. A major advantage is the short learning curve for new users.
