He-Man: Haskell Event Manager, Apropos Networking.
To test He-Man in GHC, load src/Http.hs or src/Echo.hs and type in:
compile "output_filename.c" main_loop
This will compile the program to output_filename.c, which can be passed to a C compiler and linked against the files in the src/rt directory. (A Makefile is available in src/rt.)
