/*! \brief
- * Collection of options.
+ * Base class for option managers.
+ *
+ * This class is used as a marker for all classes that are used with
+ * Options::addManager(). It doesn't provide any methods, but only supports
+ * transporting these classes through the Options collection into the
+ * individual option implementation classes.
+ *
+ * The virtual destructor is present to make this class polymorphic, such that
+ * `dynamic_cast` can be used when retrieving a manager of a certain type for
+ * the individual options.
*
- * This class provides a standard interface for implementing input options.
- * Standard usage is to write a method that creates an Options that is owned by
- * the object, populates it with supported options, and then returns it:
- * \code
- // <as class attributes>
- using gmx::Options;
- Options options("common", "Common Options");
- std::string arg1;
- int arg2;
-
- // <populating>
- using gmx::StringOption;
- using gmx::IntegerOption;
- options.addOption(StringOption("arg1").store(&arg1));
- options.addOption(IntegerOption("arg2").store(&arg2));
- return &options;
- * \endcode
- * The caller of that method can then use a parser implementation such as
- * CommandLineParser to provide values for the options.

+/*! \brief
+ * Collection of options.
*
- * Header basicoptions.h provides declarations of several standard
- * option types for use with addOption(). Documentation of those classes
- * also give more examples of how to define options.
+ * See \ref module_options for an overview of how the options work.
+ * The IOptionsContainer interface documents how to add options.
*
- * In order to keep the public interface of this class simple and to reduce
- * build dependencies on objects that simply provide options, functionality
+ * In order to keep the public interface of this class simple, functionality
* to assign values to options is provided by a separate OptionsAssigner class.
* Similarly, functionality for looping over all options (e.g., for writing out
* help) is provided by OptionsIterator.
