# autogen.sh glue for hplip

# HPLIP used to have five or so different autotools trees.  Upstream
# has reduced it to two.  Still, this script is capable of cleaning
# just about any possible mess of autoconf files.
#
# BE CAREFUL with trees that are not completely automake-generated,
# this script deletes all Makefile.in files it can find.
#
# Requires: automake 1.9, autoconf 2.57+
# Conflicts: autoconf 2.13
set -e
