If you were really planning on releasing this program for general use, you'd need to write documentation for it as well. Many people don't realize that writing good documentation is just as difficult and time-consuming—and just as important—as writing good software. However, software documentation is a subject for another book, so we'll leave you with a few references of where to learn more about documenting GNU/Linux software.
You'd probably want to write a man page for the server program, for instance. This is the first place many users will look for information about a program. Man pages are formatted using a classic UNIX formatting system troff. To view the man page for troff, which describes the format of troff files, invoke the following:
% man troff
To learn about how GNU/Linux locates man pages, consult the man page for the man command itself by invoking this:
% man man
You might also want to write info pages, using the GNU Info system, for the server and its modules. Naturally, documentation about the info system comes in info format; to view it, invoke this line:
% info info
Many GNU/Linux programs come with documentation in plain text or HTML formats as well.
Happy GNU/Linux programming!
