+## Make

+- `make debug` if you make some mistake in the code, it's a lot easier to catch it when building as debug
+it also builds the debug symbols into the binary, so you can use a c/c++ debugger (like gdb or lldb) to step through the program and see the source code as it executes
+- `make release` will turn most optimizations on and strip out all of the unnecessary stuff which is the one you'd usually use for real or for giving to other people
+- `make clean` to blow away the build/ directory
