ProgramGid(int)
Same as the -G flag if called from .init.lua for setgid()
ProgramDirectory(str)
ProgramDirectory([directory:str]) → {directory, ...}
Same as the -D flag if called from .init.lua for overlaying local
file system directories. This may be called multiple times. The
first directory programmed is preferred. These currently do not
show up in the index page listing.
This call also modifies `package.path` value to either prepend
the added directory in front of the default path (if found) or
to append it (in all other cases).
If no directory is provided, then a table with previously set
directories is returned.
ProgramLogMessages(bool)
Same as the -m flag if called from .init.lua for logging message
