+// HyperRogue: alternative build system
+// This reads the file 'hyper.cpp' and compiles the cpp files it includes into separate object files, and then links them.
+
+// Options:
+//   -O2 -- optimize
+//   -O3 -- optimize
+//   -D... -- change compilation flags
+//   [file.cpp] -- add a module to the build (e.g. ./mymake rogueviz)
