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.

		1179
		1180	AnyEvent is good for non-blocking stuff, but it can't detect file or
		1181	path changes (e.g. "watch this directory for new files", "watch this
		1182	file for changes"). The L<AnyEvent::Filesys::Notify> module promises to
		1183	do just that in a portbale fashion, supporting inotify on GNU/Linux and
		1184	some weird, without doubt broken, stuff on OS X to monitor files. It can
		1185	fall back to blocking scans at regular intervals transparently on other
		1186	platforms, so it's about as portable as it gets.

		2008	loaded.
1890		2009

		2013	C<PERL_ANYEVENT_SUBMODULE> if they have registered the AnyEvent::Submodule
		2014	namespace on CPAN, for any submodule. For example, L<AnyEvent::HTTP> could
		2015	be expected to use C<PERL_ANYEVENT_HTTP_PROXY> (it should not access env
		2016	variables starting with C<AE_>, see below).
		2017
		2018	All variables can also be set via the C<AE_> prefix, that is, instead
		2019	of setting C<PERL_ANYEVENT_VERBOSE> you can also set C<AE_VERBOSE>. In
		2020	case there is a clash btween anyevent and another program that uses
		2021	C<AE_something> you can set the corresponding C<PERL_ANYEVENT_something>
		2022	variable to the empty string, as those variables take precedence.
		2023
		2024	When AnyEvent is first loaded, it copies all C<AE_xxx> env variables
		2025	to their C<PERL_ANYEVENT_xxx> counterpart unless that variable already
		2026	exists. If taint mode is on, then AnyEvent will remove I<all> environment
		2027	variables starting with C<PERL_ANYEVENT_> from C<%ENV> (or replace them
		2028	with C<undef> or the empty string, if the corresaponding C<AE_> variable
		2029	is set).
		2030
		2031	The exact algorithm is currently:
		2032
		2033	1. if taint mode enabled, delete all PERL_ANYEVENT_xyz variables from %ENV
		2034	2. copy over AE_xyz to PERL_ANYEVENT_xyz unless the latter alraedy exists
		2035	3. if taint mode enabled, set all PERL_ANYEVENT_xyz variables to undef.
		2036
		2037	This ensures that child processes will not see the C<AE_> variables.
		2038
		2039	The following environment variables are currently known to AnyEvent:

		2070	For the rather extensive details, see L<AnyEvent::Log>.
		2071
		2072	This variable is evaluated when AnyEvent (or L<AnyEvent::Log>) is loaded,

		2074
		2075	Note that specifying this environment variable causes the L<AnyEvent::Log>
