For example, on MacOS X platforms, while most Lisps push :DARWIN to
*FEATURES*, CLISP and Allegro push :MACOS and :MACOSX instead,
respectively. Some Lisps might not push any feature suggesting MacOS
X at all. trivial-features will make sure all Lisps will have :DARWIN
in the *FEATURES* list when running on MacOS X. This way, you can
write
instead of
The included SPEC
document describes the set of symbols that should or should not be present in CL:*FEATURES*
on certain circumstances. This specification is implemented by the TRIVIAL-FEATURES system
which supports a handful of Lisps.
The test suite is, in effect, an implementation using CFFI that is
checked against the various implementations in src/tf-*.lisp.
