This package includes RTKLIB, built into the extension for the post-processing of GNSS
observations (ppk_solve):

  RTKLIB-EX v2.5.1 (https://github.com/rtklibexplorer/RTKLIB, tag v2.5.1,
  commit 62d4677ed8425a4e2748c6d390b500d1afb493fc), sources in vendor/rtklib/src, unchanged.

Not part of this package: RTKLIB's receiver decoders, streams and applications, and the routines of
the IAU SOFA library that RTKLIB bundles in sofa.c for the positions of the Sun and the Moon (an
option that is not built; SOFA has a licence of its own). See vendor/rtklib/VERSION.
