The mission of the Apache Portable Runtime (APR) project is to
create and maintain software libraries that provide a predictable
and consistent interface to underlying platform-specific
implementations. The primary goal is to provide an API to which
software developers may code and be assured of predictable if not
identical behaviour regardless of the platform on which their
software is built, relieving them of the need to code special-case
conditions to work around or take advantage of platform-specific
deficiencies or features.

list is the appropriate place.
