 I (Erik) keep a separate branch specifically set up for profiling. That branch was just forked off a local `ddc-head` branch using:

+The compiler can now be built using the `make` command.

+Once we have the profiling version of the compiler built is a matter of running it on something appropriate. I usually choose the test program in `test/90-Programs/Rover` and run is as:

+This generates a profile output file named `` which can be converted into a profile graph using:
