The exec function resident = FindResident(name) returns a pointer to
the Resident structure of a system module.  Each system library has
a Resident structure near the beginning.  The Resident structure is
described in exec/resident.h.

Those are written in BCPL so it's probably code to link themselves up
with the shared BCPL global vector (run-time library).

When the dos library creates its initial CLI, it causes it to read and
execute the commands in the file S:startup-sequence.  This is similar
to the new 1.2 FROM option for the NewCLI command.
