The CHARON-AXP/SMA(+) virtual machines are configured via a text-based configuration file.  This configuration file treats all configurable options as objects.  Each of these objects has a number of members that control specific options related to the object.

Syntax

The syntax of the CHARON-AXP/SMA(+) configuration file is very simple.  The following section describes each of the syntactic components, with examples.

Comments

All comments begin with a # character and terminate at the end of a configuration line.  They are not processed by the virtual machine.  The following example demonstrates comments both at the beginning of a line and the end of a configuration statement.

Declarations

All objects, with the exception of the built in OPA0, must be declared (or loaded) using the load command.  Most objects have extra options controlling features such as controller model.  Please see the specific object documentation for further details.  The following example demonstrates these.

Options (Configuration Object Members)

Each object is configurable using a collection of object-specific members.  These can be assigned either double-quoted string or integer values.  The following examples show the assignment of both string an integer values.
