2.2 Boot sequence

Booting THUD involves several steps.

1. Parse command-line options.
2. Reset internal data structures.
3. Display copyright and lack-of-warranty information.
4. Do add on any files specified on command-line.
5. Execute the user initialization script.
6. If not in batch mode, present a face for interactive use.

When used interactively, the command prompt (thud) lets you know THUD is ready to work. You can type in commands at the prompt and press RETURN to have THUD process them. See Command prompt expansion, for info on how to customize the prompt. Also, See Faces.

If the user initialization script file does not exist, no errors are thrown.
