runtests.sh downloads the latest ROTD from http://dl.mercurylang.org and
runs a series of bootchecks. It is designed to be run as a cron job, and
should be mostly portable to any Unix-like system (adapt as required).
Configuration occurs in the conf file. Each "test platform" can be further
customised in a conf.<platform> file.
The output is a directory of HTML and log files, to be served by a web server of your choosing.
