 26 8212662d 2004-03-15 alex # or "automake") is checked. If this fails, "tool<major><minor>" (for example
 27 8212662d 2004-03-15 alex # "automake16") and "tool-<major>.<minor>" (e. g. "autoconf-2.54") are tried
 28 8212662d 2004-03-15 alex # with <major> being 2 for tool of GNU autoconf and 1 for tools of automake;
 29 8212662d 2004-03-15 alex # <minor> is tried from 99 to 0. The first occurrence will be used.
