23 : /// Triple - Helper class for working with autoconf configuration names. For
24 : /// historical reasons, we also call these 'triples' (they used to contain
25 : /// exactly three fields).
26 : ///
27 : /// Configuration names are strings in the canonical form:
28 : /// ARCHITECTURE-VENDOR-OPERATING_SYSTEM
29 : /// or
30 : /// ARCHITECTURE-VENDOR-OPERATING_SYSTEM-ENVIRONMENT
31 : ///
32 : /// This class is used for clients which want to support arbitrary
33 : /// configuration names, but also want to implement certain special
34 : /// behavior for particular configurations. This class isolates the mapping
35 : /// from the components of the configuration name to well known IDs.
36 : ///
37 : /// At its core the Triple class is designed to be a wrapper for a triple
38 : /// string; the constructor does not change or normalize the triple string.
39 : /// Clients that need to handle the non-canonical triples that users often
40 : /// specify should use the normalize method.
41 : ///
42 : /// See autoconf/config.guess for a glimpse into what configuration names
43 : /// look like in practice.
