Each type of object that Automake understands has a special root variable name associated with it. This root is called a primary. Many actual variable names put into `Makefile.am' are constructed by adding various prefixes to a primary.
For instance, scripts--interpreted executable programs--are associated
(Note that the mysterious `bin_' prefix will be discussed later.)
The contents of a primary-derived variable are treated as targets in the
resulting `Makefile'. For instance, in our example above, we could
generate `magic-script' using
