-Woop, a HACKING document for openbox at last!
+dirs:
+       openbox - core of the WM
+       render - librender, rendering routines for the WM and for apps
+       parser - libparser, for parsing config files
 
 Beware the Client.transient_for. It can be set to a !NULL value of TRAN_GROUP,
 which is not a valid pointer. You must ALWAYS check for TRAN_GROUP before
-following transient_for. When TRAN_GROUP is found, Client.group will always
-be !NULL. Some smart action should be taken using all members of the group in
-this case.
+following transient_for. However if it is transient for the group, this
+excludes other windows whom are transient for the group, and windows which
+are children of the window (infinite loops would result)!
+
+When using coordinates/sizes of windows, make sure you use the right area. The
+Client.area rect is the reference point and size of the *CLIENT* window. This
+value is not what you see in any shape or form, and gravity is applied to it to
+translate it into what you see. The Client.frame.area is the actual position
+and size of the entire frame. This is usually the value you want to use, unless
+you are in client.c (probably) and adjusting/using the position or size from
+the client's perspective.
+
+Indentation
+-----------
+For openbox, we aim to have consistent coding style. Some, but surely
+not all, guidelines:
+ * use 4 space indents
+ * tabs should not appear in source files
+ * closing braces always go on a new line
+ * for functions, the opening brace goes on a new line
+     void foo()
+     {
+         hi;
+     }
+ * for control blocks, the opening brace goes on the same line as the
+   condition, unless the condition spans more than one line. then the brace
+   goes on a new line.
+     if (one line) {
+         hi;
+     }
+     if (first line &&
+         second line)
+     {
+         hi;
+     }
+ * always use braces around conditional blocks that consist of more than one
+   line, even if they contain a single statement
+     if (check) {
+         /* Check was true. */
+         yay = true(ok,
+                    thanks);
+     }
+ * don't need to use braces for conditional blocks that use only a single
+   line, including comments.
+     if (check)
+         all_on_one_line_so_no_braces_needed();
+ * when in doubt look at the rest of the source
+ * vim users can use "set expandtab tabstop=4 shiftwidth=4
+   softtabstop=4" for some of this
