### 9.3.49: ``superuser`'

    `superuser [value]'

Allow extra debugging information and commands. Normally, this command and the corresponding commandline flag ``-superuser`' are only used by programmers altering the Gri source.

These are the flags and their meanings:

- 1 Print cmdline before/after substituting synonyms.

- 2 Print cmdline before/after substituting rpn expressions.

- 4 Print all new commands as they are being defined

- 8 Print the system commands that are used with ``open "...|"`' and in other instances.

- 128 Changeable; only author should use this.

- 256 Changeable; only author should use this.

Note that all flags are equal to 2 raised to an integer power. Since the flag values are detected by a bitwise OR, you can combine flags by adding; thus specifying a flag of 5 yields flags 1 and 4 together; specifying 15 yields flags 1, 2, 4 and 8.
