However, rather than update the _script variables to point to the hardlinked copies of the programs, we can have the help2man steps run the existing scripts directly. This makes the relationship a bit more explicit and avoids implicit dependencies on names. * doc/local.mk: Pass $(aclocal_script) and $(automake_script) to $(update_mans). * THANKS: Add Hongxu Jia.
