Profiling a Haskell executable memory usage

To generate a heap profile from your program:

1. Compile the program for profiling.
2. Run it with one of the heap profiling options (eg. -h for a basic producer profile). This generates the file prog.hp.
3. Run hp2ps to produce a Postscript file, prog.ps.

Notes about the compilation for profiling
