@hackage optparse-th0.1.0.0

Like `optparse-generic`, but with `TemplateHaskell` for faster builds

optparse-th

This package is designed to provide a TemplateHaskell variant of optparse-generic. The Generic instance for very large sum types becomes an extremely onerous thing to compile. TemplateHaskell is able to generate the required code very quickly, which is much more efficient than going through a Generic pass that must be re-derived every time the module recompiles.
