This is Prospero release Alpha.4.5.  It is an Alpha release primarily
because the compatibility library only runs on three machine types
(the Vax, DEC MIPS, and Sun 4s).  Prospero can be run without the
compatibility library.  Instructions for installing Prospero with or
without the compatibility library can be found in INSTALLATION.

This release of Prospero includes a standalone client to query the
Archie server at McGill University (or alternative servers).  It is
standalone in the sense that, once compiled, it does not require
Prospero to be installed on the host from which it is to be used.  To
build the Archie client, first build Prospero (either with or without
the compatibility library), then connect to the user subdirectory and
type make prog.

For those interested in porting the compatibility library to a new
machine type, the relevant code is in lib/pcompat.  This directory
contains subdirectories for each machine type.  Each subdirectory
contains five almost identical five line assembly language programs,
each of which make a single system call.  Porting the library to a new
system involves replacing the program with the appropriate code for
your system type.  Once one is done, the others will be obvious.
