Ehud Gavron's INVISIBLE, based on Bruce Ellis's STEALTH and Ehud's UNSTEALTH.
Try to hide yourself on the system....

To build:

	$ MACRO INVISIBLE
	$ LINK/NOTRACE INVISIBLE

This version also changes the username in the JIB to SYSTEM.  (This is
controlled by the definition of the symbol CHANGE_USERNAME in the MACRO
source; to disable it, just comment out the following line in
INVISIBLE.MAR:

	CHANGE_USERNAME = 1

Note that commands like MAIL, SEND, REPLY, SUBMIT, etc., will all operate
under the SYSTEM username is the code is enabled.  If you want such
programs to use your own username when you are invisible, disable the code.
