The ExpressionTools package is a collection of tools for investigating the differences between pairs of expressions, typically an expected expression and another to be compared against the expected one.

The main command in this package is Compare, which compares two expressions and displays their differences.

The command Options can be used to query and set the default values for the options used by Compare.

Each command in the ExpressionTools package can be accessed by using either the long form or the short form of the command name in the command calling sequence.

The long form, ExpressionTools:-command, is always available. The short form can be used after loading the package.

The following is a list of available commands.
