It's implied later, but I should have explained at the beginning that the
first line sets up the documentation and code search lists for rclib, a
graphical tools package based on relative coordinates (hence 'rc'), which
is located at
$usepop/pop/packages/rclib
It is only available for people who have already added the packages
library, accessible at
http://www.cs.bham.ac.uk/research/projects/poplog/packages-v16.tgz
It is not (yet) part of Waldek's package, and perhaps shouldn't be included
by default.
The full current list of packages, each with its own collection of
documentation and code (including demo) libraries is
$usepop/pop/packages
(Downloadable as above.)
It's browsable online here
https://www.cs.bham.ac.uk/research/projects/poplog/packages/packages
The packages that can be added to the current poplog session using 'lib' or
'uses' are listed in
https://www.cs.bham.ac.uk/research/projects/poplog/packages/packages/lib
Some packages are parts of larger packages. E.g. the sim (simagent) package
https://www.cs.bham.ac.uk/research/projects/poplog/packages/packages/sim
includes
the objectclass package (part of the main poplog installation)
rclib
for graphical tools
poprulebase (prb)
simagent (sim)
and possibly other things I've forgotten.
This is all basically 1990s technology! But finding a good design that
provides all the benefits while using more up to date mechanisms could be a
significant project.
ISL did something like that for their Clementine data-mining package (now
part of IBM's business software but no longer implemented in Pop11).
