# This script generates the ./configure script using GNU automake and
# GNU autoconf. It tries to be smart in finding the correct/usable/available
# installed versions of these tools on your system.
#
+# In addition, it enables or disables the "de-ANSI-fication" support of GNU
+# automake, which is supported up to autoconf 1.11.x an has been removed
+# in automake 1.12 -- make sure to use a version of automake supporting it
+# when generating distribution archives!
+#
# The following strategy is used for each of aclocal, autoheader, automake,
# and autoconf: first, "tool" (the regular name of the tool, e. g. "autoconf"
# or "automake") is checked. If this fails, "tool<major><minor>" (for example
#
# 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.
# - GO=1
# and runs it with these arguments: "./configure --prefix=$HOME".
