-KWSys provides a platform-independent API to many common system
-features that are implemented differently on every platform.  This
-library is intended to be shared among many projects.
-
-How to use KWSys from ITK:
-
-#include <itkkwsys/SystemTools.hxx>
-
-bool MyIsDirectory(const char* fname)
-{
-  return itkkwsys::SystemTools::FileIsDirectory(fname);
-}
-
-How to modify KWSys:
-
-When adding a method to an existing class, make no mention of ITK.
-KWSys has no knowledge of ITK headers or libraries.  Please also keep
-in mind that KWSys must be able to build on more platforms and
-compilers than ITK.  Refer to existing code for conventions to ease
-this task.
-
-If you want to add a class, please contact the ITK mailing list for
-discussion.  Please do not add a class without permission from
-Kitware.
