+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);
+}
