%description
'cabal-helper' provides a library which wraps the internal use of anexecutable
to lift the restrictions imposed by linking against versions of GHC before
'7.10'. This has the pleasant side effect of isolating the user from having to
deal with Cabal version changes manually as 'cabal-helper' can simply recompile
it's helper program automatically as needed.

'cabal-helper' uses a wrapper executable to compile the actual cabal-helper
executable at runtime while linking against an arbitrary version of Cabal.
This runtime-compiled helper executable is then used to extract various bits
and peices from Cabal's on disk state (dist/setup-config) written by it's
configure command.

In addition to this the wrapper executable also supports installing any version
of Cabal from hackage in case it cannot be found in any available package
database. The wrapper installs these instances of the Cabal library into a
private package database so as to not interfere with the user's packages.

Furthermore the wrapper supports one special case namely reading a state file
for Cabal itself. This is needed as Cabal compiles it's Setup.hs using itself
and not using any version of Cabal installed in any package database.

'cabal-helper' can compile with 'Cabal >= 1.14' but requires 'Cabal >= 1.16' at
runtime.
