--- License     : BSD-style
--- Maintainer  : bos@serpentine.com
--- Stability   : experimental
--- Portability : GHC
---
--- Provides a shim on top of @optparse-applicative@ to define two functions:
---
--- * Define a 'tabulate' function that is backwards-compatible with
---   pre-@0.17.*@ versions of @optparse-applicative@.
--- * Define a 'text' function that is forward-compatible with
---   @optparse-applicative-0.18.*@ or later.
---
--- These are deliberately kept separate from the rest of
--- "Criterion.Main.Options" because these functions require CPP to define, and
--- there is a Haddock comment in "Criterion.Main.Options" that will cause the
--- CPP preprocessor to trigger an \"unterminated comment\" error. Ugh.
---
--- TODO: When we support @optparse-applicative-0.18@ as the minimum, remove
--- this module, and simply inline the definitions of 'tabulate' and 'text' in
--- "Criterion.Main.Options".
