debian/not-installed
List the files that are deliberately not installed in any binary package. Paths listed in this file are ignored by dh_missing. However, it is not a method to exclude files from being installed by any of the debhelper tool. If you want a tool to not install a given file, please use its --exclude option (where available).
dh_missing will expand wildcards in this file (since debhelper 11.1). Wildcards without matches will be ignored.
Supports substitution variables in compat 13 and later as documented in debhelper(7).
