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.

		2033	them also cause AnyEvent to load additional modules - for example,
		2034	C<PERL_ANYEVENT_DEBUG_WRAP> causes the L<AnyEvent::Debug> module to be
		2035	loaded.
1892		2036

		2040	C<PERL_ANYEVENT_SUBMODULE> if they have registered the AnyEvent::Submodule
		2041	namespace on CPAN, for any submodule. For example, L<AnyEvent::HTTP> could
		2042	be expected to use C<PERL_ANYEVENT_HTTP_PROXY> (it should not access env
		2043	variables starting with C<AE_>, see below).
		2044
		2045	All variables can also be set via the C<AE_> prefix, that is, instead
		2046	of setting C<PERL_ANYEVENT_VERBOSE> you can also set C<AE_VERBOSE>. In
		2047	case there is a clash btween anyevent and another program that uses
		2048	C<AE_something> you can set the corresponding C<PERL_ANYEVENT_something>
		2049	variable to the empty string, as those variables take precedence.
		2050
		2051	When AnyEvent is first loaded, it copies all C<AE_xxx> env variables
		2052	to their C<PERL_ANYEVENT_xxx> counterpart unless that variable already
		2053	exists. If taint mode is on, then AnyEvent will remove I<all> environment
		2054	variables starting with C<PERL_ANYEVENT_> from C<%ENV> (or replace them
		2055	with C<undef> or the empty string, if the corresaponding C<AE_> variable
		2056	is set).
		2057
		2058	The exact algorithm is currently:
		2059
		2060	1. if taint mode enabled, delete all PERL_ANYEVENT_xyz variables from %ENV
		2061	2. copy over AE_xyz to PERL_ANYEVENT_xyz unless the latter alraedy exists
		2062	3. if taint mode enabled, set all PERL_ANYEVENT_xyz variables to undef.
		2063
		2064	This ensures that child processes will not see the C<AE_> variables.
		2065
		2066	The following environment variables are currently known to AnyEvent:
1896		2067
1897	=over 4	2068	=over 4
1898		2069
1899	=item C<PERL_ANYEVENT_VERBOSE>	2070	=item C<PERL_ANYEVENT_VERBOSE>
1900		2071
1901	By default, AnyEvent will be completely silent except in fatal	2072	By default, AnyEvent will only log messages with loglevel C<3>
1902	conditions. You can set this environment variable to make AnyEvent more	2073	(C<critical>) or higher (see L<AnyEvent::Log>). You can set this
		2074	environment variable to a numerical loglevel to make AnyEvent more (or

		2077	If you want to do more than just set the global logging level

		2103	For the rather extensive details, see L<AnyEvent::Log>.
		2104
		2105	This variable is evaluated when AnyEvent (or L<AnyEvent::Log>) is loaded,
		2106	so will take effect even before AnyEvent has initialised itself.
		2107
		2108	Note that specifying this environment variable causes the L<AnyEvent::Log>
