+These procs may not be imported by module, you can import them for debuging:
+
+.. code-block:: nim
+  from astalgo import debug
+  from types import typeToString
+  from renderer import renderTree
+  from msgs import `??`

 To create a new compiler for each run, use ``koch temp``::
 
   ./koch temp c /tmp/test.nim
