-"""Typhon is a collection of tools for atmospheric research.

-Typhon provides:
-
-- reading and writing routines for ARTS XML files
-- an API to run and access ARTS through Python
-- conversion routines for various physical quantities
-- a tool kit to collocate different data sets (e.g. satellite, ship, ...)
-- different retrievals (e.g. QRNN, SPARE-ICE, ...)
-- a subset of the cmocean color maps
-- functions to calculate and analyse cloud masks
-- various plotting utility functions
-- functions for geodetic and geographical calculations
-- interface to the SRTM30 global elevation model
-- functions for cloudmask statistics
-- and much more...
-
-Further information on ARTS can be found on http://www.radiativetransfer.org/.
+All package metadata lives in pyproject.toml. This file only computes the
+version (mirroring typhon.__init__.py's VERSION-file read, with a
+git-describe fallback for dev builds) and passes it to setup(), which
+setuptools accepts because ``version`` is declared as dynamic.
