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.
libnewmail is a generic mail checking library.
It supports a simple API, an extensible plugin architecture
and asynchronous queries among other features.
Applications linking to libnewmail may enumerate configured mailboxes,
query mail box information and status and request a mail spool
auto-detection for users without any libnewmail specific configuration.
