KWSys provides a platform-independent API to many common system
features that are implemented differently on every platform.  The
library is intended to be shared among many projects.

How to use KWSys from ITK:

#include <itksys/SystemTools.hxx>

bool MyIsDirectory(const char* fname)
{
  return itksys::SystemTools::FileIsDirectory(fname);
}

How to modify KWSys:

When adding a method to an existing class or fixing an error/warning,
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.
