dh-exec 0.23.4build1 (ppc64el binary) in ubuntu impish

 Debhelper (in compat level 9 and above) allows its config files to be
 executable, and uses the output of such scripts as if it was the
 content of the config file.
 .
 To ease and standardize the most common tasks, this package provides
 a few solutions to help constructing such executable scripts:
 .
  * A way to ease variable substitution, from environment variables or
    dpkg-architecture.
  * Ability to filter files by architecture or build profile, within a
    single debhelper control file.
  * An extension to dh_install and dh_installman, with the ability to
    rename files.
