/**
 * @short Abstract base class for filter actions with a command line as parameter.
 *
 * Abstract base class for mail filter actions that need a command
 * line as parameter, e.g. 'forward to'. Can create a QLineEdit
 * (are there better widgets in the depths of the kdelibs?) as
 * parameter widget. A subclass of this must provide at least
 * implementations for the following methods:
 *
 * @li virtual FilterAction::ReturnCodes FilterAction::process
 * @li static FilterAction::newAction
 *
 * The implementation of FilterAction::process should take the
 * command line specified in mParameter, make all required
 * modifications and stream the resulting command line into @p
 * mProcess. Then you can start the command with @p mProcess.start().
