Coding style
------------
1. All code should be indented with tabs. (Ignore the use of only spaces in
this file) By default, source files contain the following VIM modeline:
/* vim: set ts=2 sw=2 noet: */
2. When opening new blocks such as 'while', 'if', or 'for', leave the opening
brace on the same line as the beginning of the codeblock. The closing brace
gets its own line (the only exception being 'else'). Do not use extra
spaces around the parentheses of the block. ALWAYS use opening/closing
braces, even if it's just a one-line block.
braces, even if it's just a one-line block. This reduces future error when
blocks are expanded beyond one line.

4. Comments should be ANSI-C89 compliant. That means no "// Comment" style;
use only "/* Comment */" style.

5. Return statements should be written like a function call.

7. When using strcmp() (or any function that returns 0 on success) in a
conditional statement, use != 0 or == 0 and not the negation (!) operator.
It reads much cleaner for humans (using a negative to check for success is
confusing) and the compiler will treat it correctly anyway.
