+# Simple Test Makefile
+# Mike Lam, James Madison University, August 2016
+#
+# This version of the Makefile includes support for building a test suite. The
+# recommended framework is Check (http://check.sourceforge.net/). To build and
+# run the test suite, execute the "test" target. The test suite must be located
+# in a module called "testsuite". The MODS, LIBS, and OBJS variables work as
+# they do in the main Makefile.
+#
+# To change the default build target (which executes when you just type
+# "make"), change the right-hand side of the definition of the "default"
+# target.
+#
+# By default, this makefile will build the project with debugging symbols and
+# without optimization. To change this, edit or remove the "-g" and "-O0"
+# options in CFLAGS and LDFLAGS accordingly.
+#
+# By default, this makefile build the application using the GNU C compiler,
+# adhering to the C99 standard with all warnings enabled.
+
+
+# application-specific settings and run target
