## Summary:

  A simulator for the Little Man Computer.
  https://en.wikipedia.org/wiki/Little_man_computer

  The simulator uses a plain editable buffer, so you can edit the machine
  words just like any other text, and every word can be given a name (label)
  which can also be edited in the normal way.  Additionally to the labels it
  shows the disassembled meaning of instruction words.  Of course, it can't
  always know which words are meant to be code rather than data, so it relies
  on information from the assembler to do that, and otherwise just marks every
  word it executes as being "code".

## Recent NEWS:

Since v1.4:
- Removed old backward compatibility code.
