What's here:

Mark Linimon's FreeBSD archives, snapshots of work, uploaded packages,
and so forth.  With the advent of pylon.nyi.freebsd.org, and the
effective abandonment of sparc64, most of the uploaded packages are
stale and irrelevant.

README.fixes is notes about powerpc64 ports as of June 2019.

iso/ contains downloadable FreeBSD ISO images for testing.
