Begin autotools sanitization sequence by requiring ports to explicitly
specify which version of {libtool,autoconf,automake} they need, erasing
the concept of a "system default".
For ports-in-waiting:
USE_LIBTOOL=YES -> USE_LIBTOOL_VER=13
USE_AUTOCONF=YES -> USE_AUTOCONF_VER=213
USE_AUTOMAKE=YES -> USE_AUTOMAKE_VER=14
Ports attempting to use the old style system after June 1st 2004 will be
sorely disappointed.
These are a collection of subroutines that encapsulate much
of the format-specific and tedious details of the JAM message
base format. The idea is that application programmers by
using these routines can concentrate on the more high-level
issues of their programs instead of worrying about their
JAM routines.
