• Show equations and their unknowns.

The "info" command is used to display a status report of the current set of equations. The report includes the following sections:

• A summary line counting the number of equations, variables, and unknowns.

• A numbered list of the unresolved equations alongside their unknowns.

• A list of the current set of unknown variables.

The info command can be useful in finding good candidate variables to be eliminated, or choosing which equations to use for a substitution.
