+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);
+}
