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
#+darwin foo #-darwin bar
instead of
#+(or darwin macos macosx) foo #-(or darwin macos macosx) bar
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.
