/// Triple - Helper class for working with autoconf configuration names. For
/// historical reasons, we also call these 'triples' (they used to contain
/// exactly three fields).
///
/// Configuration names are strings in the canonical form:
/// ARCHITECTURE-VENDOR-OPERATING_SYSTEM
/// or
/// ARCHITECTURE-VENDOR-OPERATING_SYSTEM-ENVIRONMENT
///
/// This class is used for clients which want to support arbitrary
/// configuration names, but also want to implement certain special
/// behavior for particular configurations. This class isolates the mapping
/// from the components of the configuration name to well known IDs.
///
/// At its core the Triple class is designed to be a wrapper for a triple
/// string; the constructor does not change or normalize the triple string.
/// Clients that need to handle the non-canonical triples that users often
/// specify should use the normalize method.
///
/// See autoconf/config.guess for a glimpse into what configuration names
/// look like in practice.
