NAME

       dh_haskell_extra_depends - generate the extra-depends file in Haskell packages

SYNOPSIS

       dh_extra_haskell_depends [debhelper options] [-Xpackage] [--exclude=package] [file ...]

DESCRIPTION

       dh_haskell_extra_depends is a debhelper program that helps with calculating dependencies
       for building Haskell libraries.

       Since Haskell libraries are statically linked, packagers that use Haskell libraries cannot
       rely on the fact that dynamical libraries are dependencies of their packages to be sure
       that possible runtime data packages are installed at execution time. The extra
       dependencies mechanism allows libraries to declare some packages that are to be added to
       the dependency list of each package that uses them to build.

       This script scans the Haskell dependencies and harvest extra dependencies information,
       putting them in the file debian/extra-depends, which is later used by dh_haskell_depends
       to be included in the substvars file.

BUGS

       None, as far as we know. :-)
