2 * `make distcheck' will enforce DESTDIR support by attempting
4 * `+=' can be used in conditionals, even if the augmented variable
5 was defined for another condition.

20 are no longer shipped, since Autoconf 2.52 provides them (both as AM_

23 * EXTRA_DIST can contain generated directories.
24 * Support for dot-less extensions in suffix rules.

37 (Note that "pkgname" is not "tarname", see the manual for details.)
38 It is also possible to pass a list of global Automake options as
39 first argument to this new form of AM_INIT_AUTOMAKE.
40 * Compiler-based assembler is now called `CCAS'; people expected `AS'
41 to be a real assembler.

73 * Can now put `.' in SUBDIRS to control build order
74 * `include' command and `+=' support for macro assignment
