Automatic Differentiation
USE Flags
ffi
Global: Use the Foreign Function Interface library (as provided by dev-java/jruby or dev-ruby/ffi depending on the implementation) rather than building a C extension to wrap around the libxml/libxslt interfaces. Note: JRuby always uses the FFI interface as native extensions are not supported.
doc
Global: Adds extra documentation (API, Javadoc, etc)
hscolour
* This flag is undocumented *
hoogle
* This flag is undocumented *
profile
Global: Adds support for software performance analysis (will likely vary from ebuild to ebuild)
test
Global: Workaround to pull in packages needed to run with FEATURES=test. Portage-2.1.2 handles this internally, so don't set it in make.conf/package.use anymore
