 DESCRIPTION
+  Keeping packages clean
     When you define a function, or import one, into a Perl package, it will
     naturally also be available as a method. This does not per se cause
     problems, but it can complicate subclassing and, for example, plugin

     If you just want to "-except" a single sub, you can pass it directly.

+  Explicitely removing functions when your scope is compiled
+    It is also possible to explicitely tell "namespace::clean" what packages
+    to remove when the surrounding scope has finished compiling. Here is an
+    example:

+      package Foo;

     Same goes for Moose::Role.
 
+  Cleaning other packages
+    You can tell "namespace::clean" that you want to clean up another
+    package instead of the one importing. To do this you have to pass in the
+    "-cleanee" option like this:
+
+      package My::MooseX::namespace::clean;
+      use strict;
+
+      use namespace::clean (); # no cleanup, just load

+    If you don't care about "namespace::clean"s discover-and-"-except"
+    logic, and just want to remove subroutines, try "clean_subroutines".

 METHODS
     You shouldn't need to call any of these. Just "use" the package at the
     appropriate place.
 
+  clean_subroutines
+    This exposes the actual subroutine-removal logic.
+
+      namespace::clean->clean_subroutines($cleanee, qw( subA subB ));
+
+    will remove "subA" and "subB" from $cleanee. Note that this will remove
+    the subroutines immediately and not wait for scope end. If you want to
+    have this effect at a specific time (e.g. "namespace::clean" acts on
+    scope compile end) it is your responsibility to make sure it runs at
+    that time.
