+/**
+* Autoload debugging
+*
+* The internal __autoload() function of the shell-wrapper has two hooks.
+* The first is called before the include is done, the second afterwards.
+*
+* we use it to track the order the includes are handled. That makes it 
+* easier to find implicit dependency problems.
+*
+* :set autoloaddebug = on
+* :set autoloaddebug = off
+*
+* the depth functions track the recursive depth of the includes. The
+* wrapper uses it to print the dots at the beginning of the line.
