Scripts to help with executable debhelper files
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.
