The CALCEPH Library is designed to access the binary planetary ephemeris files, such INPOPxx and JPL DExxx ephemeris files, and the SPICE kernel (SPK) files.

This package provides the command-line tools provided by the CALCEPH library. The CALCEPH Library is designed to access planetary ephemeris data, such INPOPxx and JPL DExxx ephemeris files, and the SPICE kernel (SPK) files.

This package provides a formalization of real analysis compatible with the Coq standard library.

SerAPI provides a library for machine-to-machine interaction with Coq with particular emphasis on integrated development environments, code analysis tools and machine learning.

QuickChick provides a framework for randomized testing of program properties ; it's a clone of Haskell's QuickCheck.

This library is a formalization of homotopy type theory for Coq, where propositional equality is interpreted as homotopy and type isomorphism as homotopy equivalence.
