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 runs on both August 24, 2022 and March 26, 2003,  it was 97 minutes
(1.62 hours) both times.  It was unexpected  for the times to come out
the same,  because a  number of things had changed between the two da-
tes.

In a run on April 07, 2024, run time was 1.25 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):
