Assigned to Fred as he's the only Unix guy around this weekend, but marked Not-a-Bug and Invalid.  Fred, how about you Close it after adding a line to the docs?  This is almost a FAQ.

The arglist passed to one of these guys becomes argv on the other end, and, as always, argv[0] is the file name associated with the file being executed.  See any manpage for execvp; this is inherited directly from how Unix(tm) defines these functions.

Comment:
Added explanation of how the first program argument (arg0 or args[0]) passed to the various exec*() functions is used.  Checked in as Doc/lib/libos.tex revision 1.47.
