+-+-+-+-+--- PLEASE NOTICE ---> this version is meant to coexist with autoconf-2.5x
+(see node Autoconf-2.5x for info documentation on latest autoconf version).
+To that end, the various binaries are actually linked to a script which
+decides which version to execute.
+Newer version (>= 2.5x) is always executed, unless pre-generated
+`configure' script exists and is generated by autoconf 2.13. You can
+also manually select this version (2.13) by setting the environment
+variable WANT_AUTOCONF_2_1 to `1'. The variable WANT_AUTOCONF_2_5 has no
+effect now.
