This directory contains the Prio source from the upstream repo:
Current version: 1.5 [commit cfecb2cc84789b9c5b2119109c5212bb297f2724]
Our in-tree copy of Prio does not depend on any generated files from the
upstream build system. Therefore, it should be sufficient to simply overwrite
the in-tree files one the updated ones from upstream to perform updates.
To simplify this, the in-tree copy can be updated by running
from within the third_party/libprio directory.
If the collection of source files changes, manual updates to moz.build may be
needed as we don't use the upstream makefiles.
