5. General Notes

WARNING: The RESTORE command has changed.  RESTORE will now
detach an attached file on a unit, if that unit did not have
an attached file in the saved configuration.  This is required
to assure that the unit flags and the file state are consistent.

WARNING: The compilation scheme for the PDP-10, PDP-11, and VAX
has changed.  Use one of the supplied build files, or read the
documentation carefully, before compiling any of these simulators.
