This directory contains the source for refer and several other programs
associated with it.  The refer subdirectory contains source for
the newest version of refer, which has been extensively modified
from the original V7 version.  The major visible changes are a new style
of citations (e.g. Jones and Smith, 1971; White et. al, 1980) with the
-m option, and improved error messages.  It requires minor changes to
the refer macros; the -ms and -me macro packages on this tape have
these changes already.  There are also major internal changes
to reduce refer's size and increase its robustness.  Refer requires
either separate I/D (use makefile) or overlays (use ovmakefile).

The util directory contains source for mkey, hunt, inv, etc., which are used
by the lookbib and pubindex scripts.  There are also sources for
the original V7 version of refer, without any bug fixes.
