/// Triple - Helper class for working with target triples.
///
-/// Target triples are strings in the format of:
+/// Target triples are strings in the canonical form:
/// ARCHITECTURE-VENDOR-OPERATING_SYSTEM
/// or
/// ARCHITECTURE-VENDOR-OPERATING_SYSTEM-ENVIRONMENT
/// behavior for particular targets. This class isolates the mapping
/// from the components of the target triple to well known IDs.
///
-/// See autoconf/config.guess for a glimpse into what they look like
-/// in practice.
+/// 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 triples look like in
+/// practice.
