/// 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
/// from the components of the target triple to well known IDs.
///
/// At its core the Triple class is designed to be a wrapper for a triple
-/// string; it does not normally change or normalize the triple string, instead
-/// it provides additional APIs to parse normalized parts out of the 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.
///
-/// One curiosity this implies is that for some odd triples the results of,
-/// e.g., getOSName() can be very different from the result of getOS(). For
-/// example, for 'i386-mingw32', getOS() will return MinGW32, but since
-/// getOSName() is purely based on the string structure that will return the
-/// empty string.
-///
-/// Clients should generally avoid using getOSName() and related APIs unless
-/// they are familiar with the triple format (this is particularly true when
-/// rewriting a triple).
-///
-/// See autoconf/config.guess for a glimpse into what they look like in
+/// See autoconf/config.guess for a glimpse into what triples look like in
