1. The Laclin source tarball  "src-haskell-packages.tgz"  was  created
using this script.

This script  requires  both Internet access and a  compatible setup at
one or more Haskell-related website[s]. It probably  won't work in the
future.

On boxes with reasonable hardware and network speeds,  the time needed
to run this script is probably on the order of 1.5 to 2.5 hours.  In a
typical run on August 24, 2022, it was:

      97 minutes (1.62 hours)

2. Requirements:

2.1. Get a copy of "cabal" 3.4.0.0 [exactly that release] built.  Name
the executable as follows  and make sure that it's accessible by PATH:

      cabal

#---------------------------------------------------------------------

2.2. Additional dependencies (not a complete list):

      Laclin
