Facebook to open source eXecutable ARchives (XARs)

Facebook has decided to pursue an open source path for its eXecutable ARchives (XARs), which is a way to create self-contained executables.

XARs, which are already being used at scale  at Facebook, are described as "a system for distributing self-contained executables that encapsulate both data and code dependencies."

Facebook says XARs are the fastest way to distribute and execute large Python applications.
