Detailed Description

Concrete implementation of an Opal simulation wrapper.

See Also: http://amas.web.psi.ch

In order to work properly the user must ensure that the environment variables

SIMTMPDIR (temporary directory for simulation input data) and
TEMPLATES (directory containing tmpl file)

are specified correctly.
