This is expected to take three commits to complete. This first initial
commit does the following:
- Begin initial rough-draft of doc/VirtualMachine.md
- Begin initial refactoring of scripts
The next commit will polish up the initial rough-draft and refactoring.
The final commit will quality-check everything and fix anything overlooked.
"Applet" is a much better name for the external command-line
scripts and programs that can be loaded as PBot commands. They
will no longer be confused with Perl modules.
