-- | Ogma: Tool to interoperate between <https://cfs.gsfc.nasa.gov/ Copilot>
-- and other languages.
--
-- Ogma is a tool to facilitate integration of safe runtime monitors into other
-- systems. It takes information from a system created in a language (e.g.,
-- CoCoSpec ) and produces specifications for the runtime verification
-- framework <https://cfs.gsfc.nasa.gov/ Copilot>. Currently, features
-- supported are:
--
-- * Translation of ptLTL and Cocospec properties defined in a
-- <https://github.com/NASA-SW-VnV/fret FRET> file into corresponding
-- expressions in Copilot.
--
-- * Translation of C headers declaring structs into the corresponding Copilot
-- Struct definitions.
--
-- * Translation of C headers declaring structs into CFS message handlers that
-- copy data in global variables.
--
-- * Generate NASA core Flight System (cFS) applications for runtime monitoring
-- using Copilot.
--
-- * Generate Robot Operating System (ROS) applications for runtime monitoring
-- using Copilot.
--
-- * Generate F' (FPrime) components for runtime monitoring using Copilot.
--
-- More information can be obtained by calling ogma with the argument @--help@.
