+);
+# USAGE
+# For details on how to use each setting, scroll down to the SETTINGS section.
+
+# QUICK START
+# * First of all, you need the libwww/LWP package installed. The package in
+# your package system is probably called something with libwww and perl and/or
+# p5 in it.
+# * /set lastfm_user to the username that you are using on Last.fm
+# * Show with /np or %np<TAB> what song "lastfm_user" last scrobbled to Last.fm via /say. If "lastfm_use_action" is set, it uses /me.
+# * To see what another user on Last.fm is playing is also possible via /np <username> or %np(<username>).
+# The now-playing message is configurable via via "lastfm_output" (and lastfm_output_tab_complete when using %np, if not set it will use lastfm_output by default.). "lastfm_strftime" can be used to configure the display of date and time when the song was scrobbled.
+
+# SETTINGS
+# NOTE: Do not set these options here, use /set <option> <value> in irssi!
+# These are just defaults and descriptions on what the options do.
+
+# The username which you are using on Last.fm
+Irssi::settings_add_str("lastfm", "lastfm_user", "");
+
+# The output that you want to use.
+# The substitution variables are:
+#   %artist = Self explanatory
+#   %album  = Self explanatory
+#   %name   = Name of song*
+#   %url    = URL to song on Last.fm
+#   %player = Player we are using to submit to Last.fm with. See setting "lastfm_get_player" below
+#   %user   = User that is playing, when /np <username> or %np(<username> is used
+# If "lastfm_output_tab_complete" is not defined, "lastfm_output" will be used instead.
+# Something bothered me for a long time and when something really starts to itch
+# I tend to want to do something about it. I'm /np:ing away displaying all sorts
+# of tracks to my friends until I get to a track which has no album information
+# on Last.fm and the output becomes really ugly "np: Kraftwerk-Aerodynamik 
+# (Alex Gopher/Etienne de Crecy dynamik mix) ()". What's with that last ()!? Oh,
+# right we are using "np: %artist-%name (%album)" as "lastfm_output". Wouldn't 
+# it be really cool if lastfm.pl knew when certain information from Last.fm
+# didn't exist and didn't display it? So thought I, so that's why I created a 
+# conditional. It works that you have to put your tag (%album e.g.) within %()
+# e.g. "np: %artist-%name%( (%album))" and everything between %( and ) only gets
+# displayed if the tag inside actually exists! Cool, huh!?
+
+#  *) Name is used instead of, the more logical IMO, track since that is what Last.fm reports in their .xml file that we parse.
+Irssi::settings_add_str("lastfm", "lastfm_output", '%(%user is )np: %artist-%name');
+Irssi::settings_add_str("lastfm", "lastfm_output_tab_complete", '');
+
+# If we should use /me instead of /say
+Irssi::settings_add_bool("lastfm", "lastfm_use_action", 0);
+
+# If we should make the subtitution variable %player available which is very slow to fetch but nice to have.
+Irssi::settings_add_bool("lastfm", "lastfm_get_player", 0);
+
+# Changelog#{{{
+
+# 5.8 -- Tue Jan 25 16:11:29 CET 2011
+# * Ignore a closure warning
+
+# 5.7 -- Mon Jan 24 16:39:06 CET 2011
+# * Fixed a bug where we forked when we still waited for a reply from last.fm
+
+# 5.6 -- Sun Jul 18 13:16:38 CEST 2010
+# * Made substitution variable %user available when /np <username> or
+# %np(<username>) is used.
+# * Made some checks a bit more strict.
+
+# 5.5 -- Mon Jul 12 19:04:26 CEST 2010
+# * Rewrote the whole error handling
+# * Fixed a bug where the error messages would be said and not printed.
+# * Fixed some minor bugs and removed some unneeded code.
+
+# 5.4 -- Wed May 26 17:04:08 CEST 2010
+# * Last.fm updated their profile HTML so that the %player macro didn't work.
+# Thanks to Keith Ward for mentioning this and suggesting a fix.
+# * A minor fix which removes some debug messages when error reporting.
+
+# 5.3 -- 
+# * I used POSIX::_exit() but I never did "use POSIX;". Leo Green, mortiis and
+# rissy reported this problem, thanks! This is an issue when you have a newer
+# version of Perl installed (>5.10)
+
+# 5.2 -- Mon Nov 16 08:25:20 CET 2009
+# * When you remove a subroutine you should remove all calls to it..
+
+# 5.1 -- Wed Nov 11 09:39:54 CET 2009
+# * Ok, I admit that using undocumented features in an API is bad, but come
+# on..  Anyway, fixed now, everything should work as it should and should
+# never break again (flw)...
+
+# 5.0 -- Mon Nov 9 08:34:48 CET 2009
+# * Fixed a warning reported by mm_mannen and did a yet another clean up
+
+# 4.9 -- Sat Nov 7 18:10:17 CET 2009
+# * Last.fm changed how their API behaved and that broke my code because
+# I'm a fool and I don't want to use an XML-lib because of your sake (so you
+# won't have to install yet another Perl-module). Thanks to supertobbe and 
+# mm_mannen who saw and reported this!
+# * Fixed so that lastfm_get_player works again and made it say that it
+# doesn't work next time Last.fm changes their HTML.
+# * Removed the date support in lastfm_output and lastfm_output_tab_complete
+# since I use the API another way now.
+# * Removed cache. It was broken at times and I can't be arsed to debug it.
+# It's not that much faster but the complexity gets bigger. If someone REALLY
+# needs this, give me a shout.
+# * Removed, rewrote and cleaned up some parts of the script.
+
+# 4.8 -- Sun May 10 10:11:29 CEST 2009
+# * Fixed a bug with the cache ('There are only two hard things in 
+# Computer Science: cache invalidation and naming things' -Phil Karlton)
+# * Started using HTML::Entities for decoding all sorts of HTML-chars, it's 
+# included in libwww anyway.
+
+# 4.7 -- Tue Apr  8 13:37:11 CEST 2009
+# * Start using LWP::UserAgent instead of LWP::Simple and got rid of the idea to
+# start using my own HTTP-lib (it was finished, but..). I'm getting old ; P
+# * Made so that everything is cached and checks if the Last-Modified date when 
+# getting information from Last.fm.
+# * Fixed some documentation bugs.
+
+# 4.6 -- Wed Mar 18 19:45:11 CET 2009
+# * Fixed an changed behavour in irssi-trunk with the error handling (which I should replace anyway!).
+# * Added %player substitute variable that shows what application you are using to scrobble with. This is very slow, so I made it an option, "lastfm_get_player".
+# * Fixed print_raw once and for all (famous last words..) so now debug output looks really neat.
+# * Added an quick start which should help get going faster
+# * Fixed an issue where %np(lastfmusername) would not work.
+# * Fixed error mesages for %np(lastfmusername)
+# * Fixed an problem with irssi-svn where die's message have changed. Thanks tto jnpplf  for reporting this.
+
+# 4.5 -- Wed  1 Oct 2008 20:03:47 CEST
+# * Removed a debug output
+# * Fixed some datacorruption, references in Perl is hard! = (
+
+# 4.4 -- Wed  1 Oct 2008 16:34:34 CEST
+# * Changed so that all the tab-commands use % instead of $ so that it's consistent through out the script.
+# * Ripped out my sprintf crap and made it more sane. You should use %artist, %album, etc in your nowplaying-setting now. Since sprintf is nolonger used I renamed that setting too.
+# * Made everything that you can set in "lastfm_output" tabable so now you can do %artist<TAB>.
+# %() in "lastfm_output" really works. It really didn't before.
+# * Fixed some issues with the date probably not working, but should now.
+# * Made the script check if Last.fm's scrobbler server is alive and kicking before we blame them.
+
+# 4.3 -- Mon 21 Jul 2008 08:46:36 CEST
+# * Seem like I misunderstood the protocol. The date/time is only sent when we have scrobbled the track, not when we started to listen to it.
+
+# 4.2 -- Tue 15 Jul 2008 15:40:08 CEST
+# Yay! Three new version within a day! (No, I'm not bored at work)
+# * Made /np username and $np(username) make username the prefix of np: yadayada or whatever your lastfm_sprintf or lastfm_sprintf_tab_complete is.
+
+# 4.1 -- Tue 15 Jul 2008 15:23:03 CEST
+# Well, that version lasted long!
+# * Fixed a bug with /np not working.
+# * Fixed an issue where debug info would be printed even if lastfm_debug was off.
+
+# 4.0 -- Tue 15 Jul 2008 10:17:51 CEST
+# * Fixing a sprintfng-bug which didn't display time if album was not set.
+# * Rewrote the whole script to use Last.fm's API which is very accurate. There is no need for $np! and /np! now, so I'm removing them.
+# * Cleaned up abit.
+
+# 3.9 -- Fri 11 Jul 2008 21:49:20 CEST
+# * Fixing a few bugs noticed by supertobbe
+
+# 3.8 -- Fri 11 Jul 2008 18:21:52 CEST
+# * Shaped up error handling and now all error messages are shown.
+# * Added a user configurable debug mode, good for sending in bugs and weird behaviour.
+# * Minor cleanup
+
+# 3.7 -- Thu 22 May 2008 10:33:55 CEST
+# * Fixed so that /np! and $np! fetches the album title too. This is horribly slow and takes approx. 6s on very fast connection. Last.fm isnt very fast I'm afraid and this is not a good way to do it.
+# * Cleaned up a few places. Started to look at the error handling and it seems to be alot of work.
+
+# 3.6 -- Tue Nov 13 15:22:37 CET 2007
+# * Fixed encoding so that it always the data into the charset that you have specified in "term_charset" which irssi also uses.
+
+# 3.5 -- Mon Nov 12 11:50:46 CET 2007
+# * Fixed the regex for parsing Recently Listened Tracks so that it works when listening with the Lastfm client.
+
+# 3.4 -- Fri Nov  9 00:23:40 CET 2007
+# * Added /np lastfmusername
+
+# 3.3 -- Tue Nov  6 01:54:59 CET 2007
+# * Finally added conditional sprintf-syntax! Let's say you want to use 'np: %s-%s (%s)' as "lastfm_sprintf". If you use /np it works out fine and displays 'np: Boards of Canada-Energy Warning (Geogaddi)' but what if you use /np! then it displays 'np: Boards of Canada-Energy Warning ()' since /np! can't get the album information. Doesn't that look ugly? Meet conditional sprintf. Now set your "lastfm_sprintf" to 'np: %s-%s%( (%s))'. ' (%s)' will only be printed if we get a third value, the album name in this case. Smart, huh? Big thanks to rindolf, apeiron and Khisanth from #perl@freenode for help with scoping with global variables.
+# * Also added "lastfm_sprintf_tab_complete" which makes, if set, $np<TAB> use a different sprintf pattern than /np. Will default back to "lastfm_sprintf".
+
+# 3.2 -- Wed Oct 24 23:07:01 CEST 2007
+# * I don't like dependencies and I really wonder why I lastfm depended on DateTime. I remember now that it was morning and I was really tired when I coded it. Anyway, it's removed now along with Socket and URI::Escape. I'll try to remove the dependency for libwww later on.
+
+# 3.1 -- Sun Oct 21 22:52:36 CEST 2007
+# * Added /np! and $np! to use the "lastfm_be_accurate_and_slow" method without having to change the setting.
+
+# 3.0 -- Fri Oct 19 14:26:03 CEST 2007
+# * Created a new setting "lastfm_be_accurate_and_slow" which makes lastfm.pl parse your profile page to check what song you are playing right now. But be warned, this is slow and horrible (like my code! ; ). But it works until Last.fm makes this data available through their Web Services. This disables the album and "scrobbled at" features of "lastfm_sprintf" so you have to adapt it if you don't want it to look weird. I'm working on a new implementation of printf which allows for conditions but it took more time than I thought and time is something that I don't have much of ='(
+
+# 2.5 -- Tue Oct  9 11:29:56 CEST 2007
+# * Fixed the encoding issue by converting from Last.fms UTF-8 into Perls internal encoding. With $np<TAB> output will be looking UTF-8-in-latin1 if you don't have an UTF-8 enabled Terminal, but it will display correctly after you have sent it.
+
+# 2.4 -- Mon Oct  8 16:08:09 CEST 2007
+# * Fixed an error in error reporting ; P Bug noticed by supertobbe = *
+# * I should make an more generic and better error reporting.
+
+# 2.3 -- Sat Oct  6 16:38:34 CEST 2007
+# * Made /np a nonblocking operation. Irssi's fork handling is REALLY messy. Thanks to tss and tommie for inspiring me in their scripts. $np cannot be made nonblocking, I'm afraid (patches welcome).
+# * Cleaned up abit.
+
+# 2.2 -- Sat Aug 18 02:20:44 CEST 2007
+# * Now you can use $np(darksoy) to see what I play (or someone else for that matter ; ).
+
+# 2.1 -- Tue Jul 17 12:50:18 CEST 2007
+# * Now you can use $np or $nowplaying as a tab-completion too, but a warning here, this is a blocking action so irssi won't respond or be usable until it is finished or the timeout is hit.
+# * Abstracted it abit more so that it can be used in more ways, ex. for the reason above.
+
+# 2.0 -- Fri Jun 29 10:38:32 CEST 2007
+# * Now you can show the time that the song was submitted in lastfm_sprintf. Added lastfm_strftime to configure how the date is presented.
+# * Added $lastfm and $lfm as tab-completions to your own Last.fm profile URL. Ripoff of Jured's guts.pl (http://juerd.nl/irssi/)
+
+# 1.5 -- Sat May 12 03:30:24 CEST 2007
+# * Started using XML instead because we get more info from it, like album (but it's often wrong).
+
+# 1.0 -- Thu Apr 12 16:57:26 CEST 2007
+# * Got fedup with no good Last.fm-based now playing scripts around.
