Plasma MapReduce and PlasmaFS - by Gerd Stolpmann, 2010-07-05
The script has even built-in knowledge about certain Linux distributions, and installs missing system packages. Nobody should stumple over libpq-dev. It can also configure PostgreSQL to some extent.
I hope this script is especially for non-ocamlers a big help, because one cannot expect knowledge about how ocaml software is usually installed. And Plasma is still missing in distros.
More information about Plasma can be found on the project page.
