+``#private`` directive
+----------------------
+
+By default c2nim marks every top level identifier (proc name, variable, etc.)
+as exported (the export marker is ``*`` in Nimrod). With the ``#private`` 
+directive identifiers can be marked as private so that the resulting Nimrod
+module does not export them. The ``#private`` directive takes a PEG pattern:
+
+.. code-block:: C
+  #private "@('_'!.)" // all identifiers ending in '_' are private
+  
+Note: The pattern refers to the original C identifiers, not to the resulting
+identifiers after mangling!

+``#skipcomments`` directive
+---------------------------
+**Note**: There is also a ``--skipcomments`` command line option that can be
+used for the same purpose.
+
+The ``#skipcomments`` directive can be put into the C code to make c2nim
+ignore comments and not copy them into the generated Nimrod file.

+
+The ``#typeprefixes`` directive can be put into the C code to make c2nim
+generate the ``T`` or ``P`` prefix for every defined type.
