# IMPORTANT!  READ ME!  YES, THAT MEANS YOU!
#
# The "versioned" autotools referenced here are for BUILDING other ports
# only.  THIS CANNOT BE STRESSED HIGHLY ENOUGH.  Things WILL BREAK if you
# try to use them for anything other than ports/ work.  This particularly
# includes use as a run-time dependency.
#
# If you need unmodified versions of autotools, such as for use in an
# IDE, then you MUST use the devel/gnu-* equivalents, and NOT these.
# See devel/anjuta and devel/kdevelop for examples.
#
# You have been WARNED!

# Compatibility shims for the old method of using autotools.  These are

#
# USE_AUTOTOOLS= tool:version[:inc | :env]  ...
#
# 'tool' can currently be one of:
#	libtool, libltdl, autoconf, autoheader, automake, aclocal
#
# 'version' is tool dependent
#
# ':inc' is for libtool only, and is used to modify the patch-autotools
#	target to use the relevant included version of libtool
#
# ':env' is for autoconf/autoheader/automake/aclocal and is used to
#	specify that the environment variables are needed, but the relevant
#	tool should NOT be run as part of the run-autotools target
#
# XXX: there is currently no sanity checking of the supplied variables
#	other than to detect actually available versions.  This should
#	probably be fixed at some point.
#
# In addition, the following 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
#
# LIBTOOLFLAGS=<value>
#	- Arguments passed to libtool during configure step
#	  Currently defaults to "--disable-ltlibs", but this will be going
#	  away when libtool .la files are brought back
#
# LIBTOOLFILES=<list-of-files>
#	- A list of files to patch during libtool pre-configuration
#	  Defaults to "aclocal.m4" if autoconf is in use, otherwise "configure"
