Woop, a HACKING document for openbox at last!
+dirs:
+ kernel - 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.
+ Smart action idea:
+ Skip over members of the group that are also transients of the group
+ (have Client.transient_for set to TRAN_GROUP). These windows are not
+ ancestors and using them will also end up causing infinite loops!
+
+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
+ * functions should have the opening and closing braces on their own
+ lines
+ * most other constructs should have braces on the same line as the
+ statement
+ * 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
