Coding style guidelines
=======================

You should set tabs to display as eight spaces, not four.  However, 
_indentation_ should be four spaces.  If possible, do not use tab
characters at all.  There is a utility called "expand" which will
remove tab characters.

Please write code to an 80 column limit so that it fits within a 
standard 80 column terminal.

Functions should be named like this: 'AB_FunctionName'.  The 'AB' prefix 
denotes the subsystem (AM_ for automap, G_ for game, etc).  If a 
function is static, you can omit the prefix and just name it like
'FunctionName'.  Functions and global variables should always be
made static if possible.

Put '_t' on the end of types created with typedef.  Type names like this
should be all lowercase and have the subsystem name at the start. An
example of this is 'txt_window_t'.  When creating structures, always
typedef them.

Do not use the goto statement.

Use C++-style comments, ie. '//' comments, not '/* ... */' comments.
I don't care that this isn't standard C.

Variables should be named like this: 'my_variable_name', not like
this: 'MyVariableName'.  In pointer variable declarations, place
the '*' next to the variable name, not the type.

When using an if, do, while, or for statement, always use the { }
braces even when they are not necessary.  For example, do this:

    if (condition)
    {
        body;
    }

Not this:

    if (condition)   // NO
        body;

Write code like this:

typedef struct
{
    int member1;
    char *member2;
} my_structure_t;

void FunctionName(int argument, int arg2, int arg3, int arg4, int arg5, 
                  int arg6, int arg7)
{
    if (condition)
    {
        body;
    }
    else if (condition)
    {
        body;
    }
    else 
    {
        body;
    }

    if (very_long_condition_like_this_one_that_forces_a_line_break
     && other_condition)
    {
        body;
    }

    switch (argument)
    {
        case FIRST:
            code;
            break;
            
        case SECOND:
            code;
            break;
            
        default:
            break;
    }

    for (a=0; a<10; ++a)
    {
        loop_body;
    }

    while (a < 10)
    {
        loop_body;
    }

    do 
    {

    } while (condition);
}
