 =head1 DESCRIPTION
 This module implements a relatively simple "logging framework". It doesn't
 attempt to be "the" logging solution or even "a" logging solution for
 AnyEvent - AnyEvent simply creates logging messages internally, and this
 module more or less exposes the mechanism, with some extra spiff to allow
 using it from other modules as well.
-Remember that the default verbosity level is C<0> (C<off>), so nothing
+Remember that the default verbosity level is C<4> (C<error>), so only
-will be logged, unless you set C<PERL_ANYEVENT_VERBOSE> to a higher number
+errors and more important messages will be logged, unless you set
-before starting your program, or change the logging level at runtime with
+C<PERL_ANYEVENT_VERBOSE> to a higher number before starting your program
-something like:
+(C<AE_VERBOSE=5> is recommended during development), or change the logging
+level at runtime with something like:
    use AnyEvent::Log;
    $AnyEvent::Log::FILTER->level ("info");
 The design goal behind this module was to keep it simple (and small),
 numerical value".
 Instead of specifying levels by name you can also specify them by aliases:
    LVL NAME      SYSLOG   PERL  NOTE
-   1   fatal     emerg    exit  aborts program!
+    1  fatal     emerg    exit  system unusable, aborts program!
-   2   alert
+    2  alert                    failure in primary system
-   3   critical  crit
+    3  critical  crit           failure in backup system
-   4   error     err      die
+    4  error     err      die   non-urgent program errors, a bug
-   5   warn      warning
+    5  warn      warning        possible problem, not necessarily error
-   6   note      notice
+    6  note      notice         unusual conditions
-   7   info
+    7  info                     normal messages, no action required

-   9   trace
+    9  trace                    copious tracing output
 As you can see, some logging levels have multiple aliases - the first one
 is the "official" name, the second one the "syslog" name (if it differs)
-and the third one the "perl" name, suggesting that you log C<die> messages
+and the third one the "perl" name, suggesting (only!) that you log C<die>
-at C<error> priority.
+messages at C<error> priority. The NOTE column tries to provide some
+rationale on how to chose a logging level.
+As a rough guideline, levels 1..3 are primarily meant for users of the
+program (admins, staff), and are the only ones logged to STDERR by
+default. Levels 4..6 are meant for users and developers alike, while
+levels 7..9 are usually meant for developers.
-You can normally only log a single message at highest priority level
+You can normally only log a message once at highest priority level (C<1>,
-(C<1>, C<fatal>), because logging a fatal message will also quit the
+C<fatal>), because logging a fatal message will also quit the program - so
-program - so use it sparingly :)
+use it sparingly :)
+For example, a program that finds an unknown switch on the commandline
+might well use a fatal logging level to tell users about it - the "system"
+in this case would be the program, or module.
 Some methods also offer some extra levels, such as C<0>, C<off>, C<none>

 Requests logging of the given C<$msg> with the given log level, and
 returns true if the message was logged I<somewhere>.
-For C<fatal> log levels, the program will abort.
+For loglevel C<fatal>, the program will abort.
 If only a C<$msg> is given, it is logged as-is. With extra C<@args>, the
 C<$msg> is interpreted as an sprintf format string.
 The C<$msg> should not end with C<\n>, but may if that is convenient for
 Last not least, C<$msg> might be a code reference, in which case it is
 supposed to return the message. It will be called only then the message
 actually gets logged, which is useful if it is costly to create the
 message in the first place.
+This function takes care of saving and restoring C<$!> and C<$@>, so you
+don't have to.
 Whether the given message will be logged depends on the maximum log level
 and the caller's package. The return value can be used to ensure that
 messages or not "lost" - for example, when L<AnyEvent::Debug> detects a
 runtime error it tries to log it at C<die> level, but if that message is

 This is a convenience constructor that makes it simpler to construct
 anonymous logging contexts.
 =item $ctx->disable ($level[, $level...])
 Disables logging for the given levels, leaving all others unchanged.
+=item $ctx->cap ($level)
+Caps the maximum priority to the given level, for all messages logged
+to, or passing through, this context. That is, while this doesn't affect
+whether a message is logged or passed on, the maximum priority of messages
+will be limited to the specified level - messages with a higher priority
+will be set to the specified priority.
+Another way to view this is that C<< ->level >> filters out messages with
+a too low priority, while C<< ->cap >> modifies messages with a too high
+priority.
+This is useful when different log targets have different interpretations
+of priority. For example, for a specific command line program, a wrong
+command line switch might well result in a C<fatal> log message, while the
+same message, logged to syslog, is likely I<not> fatal to the system or
+syslog facility as a whole, but more likely a mere C<error>.
+This can be modeled by having a stderr logger that logs messages "as-is"
+and a syslog logger that logs messages with a level cap of, say, C<error>,
+or, for truly system-critical components, actually C<critical>.

 =head1 EXAMPLES
 This section shows some common configurations, both as code, and as
 C<PERL_ANYEVENT_LOG> string.
 This writes them only when the global logging level allows it, because
 it is attached to the default context which is invoked I<after> global
 filtering.
-   $AnyEvent::Log::FILTER->attach
+   $AnyEvent::Log::FILTER->attach (
       new AnyEvent::Log::Ctx log_to_file => $path);
    PERL_ANYEVENT_LOG=filter=+%filelogger:%filelogger=file=/some/path
 This writes them regardless of the global logging level, because it is
    PERL_ANYEVENT_LOG=%filelogger=file=/some/path:collect=+%filelogger
 In both cases, messages are still written to STDERR.
+=item Additionally log all messages with C<warn> and higher priority to
+C<syslog>, but cap at C<error>.
+This logs all messages to the default log target, but also logs messages
+with priority C<warn> or higher (and not filtered otherwise) to syslog
+facility C<user>. Messages with priority higher than C<error> will be
+logged with level C<error>.
+   $AnyEvent::Log::LOG->attach (
+      new AnyEvent::Log::Ctx
+         level  => "warn",
+         cap    => "error",
+         syslog => "user",
+   );
+   PERL_ANYEVENT_LOG=log=+%syslog:%syslog=warn,cap=error,syslog
 =item Write trace messages (only) from L<AnyEvent::Debug> to the default logging target(s).
 Attach the C<$AnyEvent::Log::LOG> context to the C<AnyEvent::Debug>
 context - this simply circumvents the global filtering for trace messages.
