Here are a few resources for those among you thinking of writing proper documentation for your new project, or to contribute writings or translations to your favorite Community.
Man pages are written in Troff, the original UNIX typesetting system. Nowadays, few people (most notably man page writers and IETF RFC authors) regularly use this markup, but it is rather simple and elegant once you get to know it. For writing man pages, the learning curve is very good, as you only need to know a few macros and, just as if you were working on html and pilfering the sources of an existing page doing just what you need, you have a wealth of examples to teach you right there on your trusty *NIX box. As the Wikipedia points out:
Troff features commands to designate fonts, spacing, paragraphs, margins, footnotes and more. Unlike many other text formatters, troff can position characters arbitrarily on a page, even overlapping them, and has a fully programmable input language. Separate preprocessors are used for more convenient production of tables, diagrams, and mathematics.
But you don’t need to master all that! For man pages, what you need is knowledge of the man macro package, originally written by James Clark and documented in man(7) or groff_man(7) depending on your distro. Troff input is processed from text files, so you just need your favorite text editor, and a bit of time to play with the markup to learn it in the process.
Here is a way to get started quickly: Linux Journal published a great tutorial a few years back, and the Linux Manual contains the ever-important style guidelines in man-pages(7). Start from scratch, or make a copy of an existing manual page and start editing. One more tip for you:
is your friend, to see what you just wrote and marked up in all its glory — and bugs.
