Quickstart instructions (for hackers):

• Check out sources from git (clbuild also has it.)
  
• Build it: Generate the hemlock executable core file:
  $ ./build.sh
  
• Run it:
  $ ./hemlock
$ ./hemlock --help

You can work without a core file if you load the asdf system hemlock.tty or hemlock.clx and run (ed) manually. (From slime, that works better with clx than tty, because the tty backend needs a tty…)
