## OpenLIBM

OpenLIBM contains code that is covered by various licenses. 

The OpenLIBM code derives from the FreeBSD msun implementation, which
in turn derives from FDLIBM 5.3. As a result, it has a number of fixes
and updates that have accumulated over the years in msun, and also
optimized assembly versions of many functions. These improvements are
provided under the BSD license. The msun library also includes work
placed under the public domain, whih is noted in the individual
files. Further work on making a standalone OpenLIBM library from msun,
as part of the Julia project is covered under the MIT license.
