/*
 * This file implements a simple client of the SIL library which serves
 * two purposes: it demonstrates how a program can use the SIL build system
 * to build an executable, and it allows the internal SIL tests to be run
 * with a "-test" command-line parameter.
 *
 * See the Makefile in the build/ subdirectory of this directory for
 * details on how to use the SIL build system.
