# To build on Unix/Mac/Windows: make

# To build debuggable executable, add DEBUG=1 to cmd-line invocation
# By default, 32-bit binary is built.  To build a 64-bit binary, add BITS=64 to the cmd-line invocation
# Override MODULE on the cmd-line invocation if you want to build a custom named executable, e.g. 'simc64'
# Override OBJ_DIR if you want your object files built somewhere other than the local directory
