5.1 Common Behavior
===================

Much effort has been expended to make Autoconf easy to learn.  The most

and behaviors, avoiding exceptions as much as possible.  Because of
history and inertia, unfortunately, there are still too many exceptions
in Autoconf; nevertheless, this section describes some of the common
rules.
