Module Name:

    escptest.c

Abstract:

    Test module for NLS API EnumSystemCodePages.

    NOTE: This code was simply hacked together quickly in order to
          test the different code modules of the NLS component.
          This is NOT meant to be a formal regression test.

Revision History:

    08-02-93    JulieB    Created.
