# IMPORTANT NOTE:
#	Before making any changes to this file, contact portmgr to arrange
#	for an experimental ports run.
#	Untested commits will almost certainly break the tree, incur the
#	wrath of countless folks, and be unceremoniously backed out by
#	the maintainer and/or portmgr.

# USE_AUTOTOOLS= tool[:env] ...
#
# 'tool' can currently be one of the following:
#	autoconf, autoheader
#	automake, aclocal
#	libtoolize
#
# ':env' is used to specify that the environmental variables are needed
#	but the relevant tool should NOT be run as part of the
#	'run-autotools' target
#
# In addition, these variables can be set in the port Makefile to be
# passed to the relevant tools:
#
# AUTOMAKE_ARGS=...
#	- Extra arguments passed to automake during configure step
#
# ACLOCAL_ARGS=...
#	- Arguments passed to aclocal during configure step
#
# AUTOCONF_ARGS=...
#	- Extra arguments passed to autoconf during configure step
#
# AUTOHEADER_ARGS=...
#	- Extra arguments passed to autoheader during configure step
#
# LIBTOOLIZE_ARGS=...
#	- Extra arguments passed to libtoolize during configure step
