# This script generates the ./configure script using GNU automake and
# GNU autoconf. It tries to be smart in finding the correct/usable/available
#
# You can tweak the behaviour using these environment variables:
#
-# - ALICA=<cmd>, AUTOHEADER=<cmd>, AUTOMAKE=<cmd>, AUTOCONF=<cmd>
+# - ACLOCAL=<cmd>, AUTOHEADER=<cmd>, AUTOMAKE=<cmd>, AUTOCONF=<cmd>
# Name and optionally path to the particular tool.
# - PREFIX=<path>
# Search the GNU autoconf and GNU automake tools in <path> first. If the
# generated ./configure script will be called, pass "--prefix=<path>" to it.
+# - EXIST=<tool>
+# Use <tool> to test for aclocal, autoheader etc. pp. ...
+# When not specified, either "type" or "which" is used.
# - VERBOSE=1
# Output the detected names of the GNU automake and GNU autoconf tools.
