haskell-devscripts binary package in Ubuntu Jammy amd64

 This package provides a collection of scripts to help build Haskell
 packages for Debian. Unlike haskell-utils, this package is not
 expected to be installed on the machines of end users.
 .
 This package is designed to support Cabalized Haskell libraries. It
 is designed to build a library for each supported Debian compiler or
 interpreter, generate appropriate postinst/prerm files for each one,
 generate appropriate substvars entries for each one, and install the
 package in the Debian temporary area as part of the build process.
 .
 This package is actually an empty package and is only useful for its
 dependency on hscolour.
