/// # Description {#bdlat_enumeratorinfo-description}
///
/// This component provides the `bdlat_EnumeratorInfo` `class` which is a
/// container for holding information (properties) about an enumerator.  The
/// properties of an enumerator include its name and the length of its name, its
/// value, and a brief annotation.  Although each enumerator property is
/// publicly accessible, a manipulator and accessor is also supplied for each.
///
/// ## Usage {#bdlat_enumeratorinfo-usage}
///
///
/// This section illustrates intended use of this component.
///
/// ### Example 1: Basic Usage {#bdlat_enumeratorinfo-example-1-basic-usage}
