A compliant debian binary package can have maintainer scripts (postinst, postrm, prerm, postrm) that are executed by the package management tool. https://www.debian.org/doc/debian-policy/ch-maintainerscripts.html#package-maintainer-scripts-and-installation-procedure These scripts are very common in Debian Packages and primordial for them to be properly managed in the Ubuntu distro. debcraft should be able to allow: - developers to write the contents of these scripts - allow various current and future helpers to inject contents to these scripts to lower the developers burden.
