+# MINGW32 Makefile for EPANET

+# This will build EPANET as DLL
+# (epanet2.dll) under MINGW32 GCC, and a standalone
+# executable (epanet2d.exe).
+
+# The following targets are defined:
+# make
+#     -Builds epanet2.dll, epanet2d.exe
+# make install
+#     -Copy epanet2.dll, epanet2d.exe, epanet2.def to $(prefix)
+# make clean
+#     -Removes object and library files, returning the build directory
+#      to its pristine state.
+
+# You may wish to change the install path 'prefix',
+# or the compiler flags, but these defaults should be fine.
