Module Name:

    eslgtest.c

Abstract:

    Test module for NLS API EnumSystemLanguageGroups.

    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:

    03-10-98    JulieB    Created.
