I use emacs, and the C and C++ modes. The following magic will get emacs into
the mode I use:
-*- Mode: C; tab-width: 8; indent-tabs-mode: nil; c-basic-offset: 4 -*-
Thats what I would like all the contributed code formated as. 
If its not it will be. 

Functions should not consume more then a page of code. (80x24) The exception
would be large case statements, With those each case should be directed 
out to a function for that case. Let the compiler optimize.

functions shall be defined as such:

/**
 * <function name>:
 * @args
 *
 * What it does
 *
 * Return value:
 **/
<return value>
<function> (<arguments>)
{
 /* function body */
}

Disabling code shall be done with #if/#endif constructs with a comment
as to why the code is disabled.
