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.
XXL is a library for C and C++ that provides exception handling
and asset management. Asset management is integrated with the
exception handling mechanism such that assets may be
automatically cleaned up if an exception is thrown, which
allows for much simplified program structure with respect to
error handling.
By allowing XXL to track assets and using its exception
handling features, the programmer no longer has to check error
conditions on every function call and cleanup the assets on
failure because XXL does the work.
