-- | Discovers the location of 'ghc-pkg' given the absolute path to 'ghc'
-- and its '$libdir' (obtainable by running @ghc --print-libdir@).
--
-- @'withGhcPkgTool' ghcPathAbs libdir@ guesses the location by looking at
-- the filename of 'ghcPathAbs' and expects that 'ghc-pkg' is right next to it,
-- which is guaranteed by the ghc build system. Most OS's follow this
-- convention.
--
-- On unix, there is a high-chance that the obtained 'ghc' location is the
-- "unwrapped" executable, e.g. the executable without a shim that specifies
-- the '$libdir' and other important constants.
-- As such, the executable 'ghc-pkg' is similarly without a wrapper shim and
-- is lacking certain constants such as 'global-package-db'. It is, therefore,
-- not suitable to pass in to other consumers, such as 'cabal'.
--
-- Here, we restore the wrapper-shims, if necessary, thus the returned filepath
-- can be passed to 'cabal' without further modifications.
