Description-en: abstraction layer for the *FEATURES* across Common Lisp implementations
trivial-features ensures consistent *FEATURES* across multiple Common
Lisp implementations.
.
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
