4 # Usage:
5 # Call this script from debian/rules, before dh_gencontrol is run,
6 # to get all needed variables computed in debian/$p.substvars for
7 # each package $p found through dh_listpackages.
8 # .
9 # This script has support for udebs.

13 if ! which dh_listpackages >/dev/null 2>&1; then
14 echo "E: dh_listpackages not found, debhelper package missing?"
15 exit 1
