1150	Here be danger!
1151
1152	As Pauli would put it, "Not only is it not right, it's not even wrong!" -
1153	there are so many things wrong with AnyEvent::Handle::UDP, most notably
1154	its use of a stream-based API with a protocol that isn't streamable, that
1155	the only way to improve it is to delete it.
1156
1157	It features data corruption (but typically only under load) and general
1158	confusion. On top, the author is not only clueless about UDP but also
1159	fact-resistant - some gems of his understanding: "connect doesn't work
1160	with UDP", "UDP packets are not IP packets", "UDP only has datagrams, not
1161	packets", "I don't need to implement proper error checking as UDP doesn't
1162	support error checking" and so on - he doesn't even understand what's
1163	wrong with his module when it is explained to him.

		1181
		1182	AnyEvent is good for non-blocking stuff, but it can't detect file or
		1183	path changes (e.g. "watch this directory for new files", "watch this
		1184	file for changes"). The L<AnyEvent::Filesys::Notify> module promises to
		1185	do just that in a portbale fashion, supporting inotify on GNU/Linux and
		1186	some weird, without doubt broken, stuff on OS X to monitor files. It can
		1187	fall back to blocking scans at regular intervals transparently on other
		1188	platforms, so it's about as portable as it gets.

		2017	C<PERL_ANYEVENT_SUBMODULE> if they have registered the AnyEvent::Submodule
		2018	namespace on CPAN, for any submodule. For example, L<AnyEvent::HTTP> could
		2019	be expected to use C<PERL_ANYEVENT_HTTP_PROXY> (it should not access env
		2020	variables starting with C<AE_>, see below).
		2021
		2022	All variables can also be set via the C<AE_> prefix, that is, instead
		2023	of setting C<PERL_ANYEVENT_VERBOSE> you can also set C<AE_VERBOSE>. In
		2024	case there is a clash btween anyevent and another program that uses
		2025	C<AE_something> you can set the corresponding C<PERL_ANYEVENT_something>
		2026	variable to the empty string, as those variables take precedence.
		2027
		2028	When AnyEvent is first loaded, it copies all C<AE_xxx> env variables
		2029	to their C<PERL_ANYEVENT_xxx> counterpart unless that variable already
		2030	exists. If taint mode is on, then AnyEvent will remove I<all> environment
		2031	variables starting with C<PERL_ANYEVENT_> from C<%ENV> (or replace them
		2032	with C<undef> or the empty string, if the corresaponding C<AE_> variable
		2033	is set).
		2034
		2035	The exact algorithm is currently:
		2036
		2037	1. if taint mode enabled, delete all PERL_ANYEVENT_xyz variables from %ENV
		2038	2. copy over AE_xyz to PERL_ANYEVENT_xyz unless the latter alraedy exists
		2039	3. if taint mode enabled, set all PERL_ANYEVENT_xyz variables to undef.
		2040
		2041	This ensures that child processes will not see the C<AE_> variables.
		2042
		2043	The following environment variables are currently known to AnyEvent:
1896		2044
1897	=over 4	2045	=over 4

		2080	For the rather extensive details, see L<AnyEvent::Log>.
		2081
		2082	This variable is evaluated when AnyEvent (or L<AnyEvent::Log>) is loaded,
		2083	so will take effect even before AnyEvent has initialised itself.
		2084
		2085	Note that specifying this environment variable causes the L<AnyEvent::Log>
		2086	module to be loaded, while C<PERL_ANYEVENT_VERBOSE> does not, so only
