Support for package databases
data PackageDB
Some compilers have a notion of a database of available packages. For some there is just one global db of packages, other compilers support a per-user or an arbitrary db specified at some location in the file system. This can be used to build isloated environments of packages, for example to build a collection of related packages without installing them globally.

type Flag = String
extensionsToFlags :: Compiler -> [Extension] -> [Flag]
For the given compiler, return the flags for the supported extensions.
unsupportedExtensions :: Compiler -> [Extension] -> [Extension]
For the given compiler, return the flags for the supported extensions.
