#                             explanation
#---------------------------------------------------------------------

1. The  Laclin source tarball "src-cabal3400.base.tgz" was created us-
ing 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.

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

2. Requirements:

2.1. Get a copy of "cabal" 2.4.0.0 built.  Name the executable as fol-
lows and make sure that it's accessible by PATH:

      cabal2400

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

2.2. Additional dependencies (not a complete list):
