# This is the default prerm file from the blends-dev package which is used
# in all meta packages. If there is a certain need to provide extra
# prerm files for some meta packages this template will be appended. Thus
# it will be checked whether debconf was just initialized.
#
# You should not insert the _DEBHELPER_ template in the special postscript
# file because it is in the end of this template anyway.

# Debian Edu there is no need to install blends-common package. Thus we
# have to make sure that postinst does not try to include the menu stuff
# The most portable way to test a program for existence
# This fixes https://lintian.debian.org/tags/command-with-path-in-maintainer-script.html
