+# This script will remove all traces of Haskell and GHC and Cabal from your debian
+# system and install ghc-7.0.3 and the Haskell Platform. Then it will install
+# Pugs. Good luck abd patience. You'll need both in spades.
+#
+# Usage:
+#   PLATFORM=i386 ./install-haskell-platform-ghc7-and-pugs-on-debian-or-ubuntu-from-scratch.sh
+# 
+# Where PLATFORM is one of the values below:
+#
+# PLATFORM=i386
+# PLATFORM=x86_64
+
+if [ -z "$PLATFORM" ]; then
+    echo "You need to set PLATFORM environment variable to i386 or x86_64"
+    exit 1
+fi
+
+# Start with a Haskell-free system:
+sudo apt-get purge haskell-platform ghc
+sudo apt-get autoremove
+rm -fr ~/.cabal
+
+# Install debian deps for haskell-platform
+sudo apt-get install libgmp3-dev libedit2 libedit-dev freeglut3-dev libglu1-mesa-dev
+# Install debian deps for pugs
+sudo apt-get install libperl-dev libncurses-dev libncurses5-dev
