-# UPGRADE NOTE
-# ============
-# for users of 0.7 or earlier series, please note that appearance
-# settings have moved to /format, i.e. inside your theme!
-# the fifo (screen) has been replaced by an external viewer script
-
-# Usage
-# =====
-# copy the script to ~/.irssi/scripts/
-#
-# In irssi:
-#
-#		/run adv_windowlist
-#
-# In your shell (for example a tmux split):
-#
-#		perl ~/.irssi/scripts/adv_windowlist.pl
-#
-# To use sbar mode instead:
-#
-#		/toggle awl_viewer
-#
-# Hint: to get rid of the old [Act:] display
-#     /statusbar window remove act
-#
-# to get it back:
-#     /statusbar window add -after lag -priority 10 act
-
-# Options
-# =======
-# formats can be cleared with /format -delete
-#
-# /format awl_display_(no)key(_active|_visible) <string>
-# * string : Format String for one window. The following $'s are expanded:
-#     $C : Name

-#     $Q : meta-Keymap
-#     $H : Start hilighting
-#     $S : Stop hilighting
-#         /+++++++++++++++++++++++++++++++++,
-#        | ****  I M P O R T A N T :  ****  |
-#        |                                  |
-#        | don't forget  to use  $S  if you |
-#        | used $H before!                  |
-#        |                                  |

-# * this setting decides whether awl will use the active_name (OFF) or the
-#   window name as the name/caption in awl_display_*.
-#   That way you can rename windows using /window name myownname.
-#
-# /set awl_hide_empty <num>
-# * if visible windows without items should be hidden from the window list
-# set it to 0 to show all windows
-#           1 to hide visible windows without items (negative exempt
-#           active window)
-#
-# /set awl_detach <list>
-# * list of windows that should be hidden from the window list. you
-#   can also use /awl detach and /awl attach to manage this
-#   setting. an optional data_level can be specified with ",num"
-#
-# /set awl_detach_data <num>
-# * num : hide the detached window if its data_level is below num

-#   activity_hide_targets setting
-#
-# /set awl_hide_data <num>

-#           2 to show only those windows with channel text or hilight
-#           3 to show only windows with hilight (negative exempt active window)
-#
-# /set awl_hide_name_data <num>
-# * num : hide the name of the window if its data_level is below num
-#   (only works in status bar without block display)
-# you will want to change your formats to add $H...$S around $Q or $N
-# if you plan to use this
-#
-# /set awl_maxlines <num>
-# * num : number of lines to use for the window list (0 to disable, negative
-#   lock)
-#
-# /set awl_maxcolumns <num>
-# * num : number of columns to use for the window list when using the
-#   tmux integration (0 to disable)
-#
-# /set awl_block <num>

-#        |                                  |
-#        | If  your  block  display  looks  |
-#        | DISTORTED,  you need to add the  |
-#        | following  line to your  .theme  |

-#        '+++++++++++++++++++++++++++++++++/
-#
-# /set awl_sbar_maxlength <ON|OFF>
-# * if you enable the maxlength setting, the block width will be used as a
-#   maximum length for the non-block status bar mode too.
-#
-# /set awl_height_adjust <num>
-# * num : how many lines to leave empty in viewer mode
-#
-# /set awl_sort <-data_level|-last_line|refnum>
-# * you can change the window sort order with this variable
-#     -data_level : sort windows with hilight first
-#     -last_line  : sort windows in order of activity
-#     refnum      : sort windows by window number
-#     active/server/tag : sort by server name
-#     lru         : sort windows with the last recently used last
-#   "-" reverses the sort order
-#   typechecks are supported via ::, e.g. active::Query or active::Irc::Query
-#   undefinedness can be checked with ~, e.g. ~active
-#   string comparison can be done with =, e.g. name=(status)
-#   to make sort case insensitive, use #i, e.g. name#i
-#   any key in the window hash can be tested, e.g. active/chat_type=XMPP
-#   multiple criteria can be separated with , or +, e.g. -data_level+-last_line
-#
-# /set awl_placement <top|bottom>
-# /set awl_position <num>
-# * these settings correspond to /statusbar because awl will create
-#   status bars for you
-# (see /help statusbar to learn more)
-#
-# /set awl_all_disable <ON|OFF>
-# * if you set awl_all_disable to ON, awl will also remove the
-#   last status bar it created if it is empty.
-#   As you might guess, this only makes sense with awl_hide_data > 0 ;)
-#
-# /set awl_viewer <ON|OFF>
-# * enable the external viewer script
-#
-# /set awl_viewer_launch <ON|OFF>
-# * try to auto-launch the viewer under tmux or with a shell command
-#   /awl restart is required all auto-launch related settings to take
-#   effect
-#
-# /set awl_viewer_tmux_position <left|top|right|bottom|custom>
-# * try to split in this direction when using tmux for the viewer
-#   custom : use custom_command setting
-#
-# /set awl_viewer_xwin_command <shell command>
-# * custom command to run in order to start the viewer when irssi is
-#   running under X
-#   %A  - gets replaced by the command to run the viewer
-#   %qA - additionally quote the command
-#
-# /set awl_viewer_custom_command <shell command>
-# * custom command to run in order to start the viewer
-#
-# /set awl_viewer_launch_env <string>
-# * specific environment settings for use on viewer auto-launch,
-#   without the AWL_ prefix
-#
-# /set awl_shared_sbar <left<right|OFF>
-# * share a status bar for the first awl item, you will need to manually
-#   /statusbar window add -after lag -priority 10 awl_shared
-#     left   : space in cells occupied on the left of status bar
-#     right  : space occupied on the right
-# Note: you need to replace "left" AND "right" with the appropriate numbers!
-#
-# /set awl_path <path>
-# * path to the file which the viewer script reads
-#
-# /set fancy_abbrev <no|head|strict|fancy>
-# * how to shorten too long names
-#     no     : shorten in the middle
-#     head   : always cut off the ends
-#     strict : shorten repeating substrings
-#     fancy  : combination of no+strict
-#
-# /set awl_custom_xform <perl code>
-# * specify a custom routine to transform window names
-#   example: s/^#// remove the #-mark of IRC channels
-#   the special flags $CHANNEL / $TAG / $QUERY / $NAME can be
-#   tested in conditionals
-#
-# /set awl_last_line_shade <timeout>
-# * set timeout to shade activity base colours, to enable
-#   you also need to add +-last_line to awl_sort
-#   (requires 256 colour support)
-#
-# /set awl_no_mode_hint <ON|OFF>
-# * whether to show the hint of running the viewer script in the
-#   status bar
-#
-# /set awl_mouse <ON|OFF>
-# * enable the terminal mouse in irssi
-# (use the awl-patched mouse.pl for gestures and commands if you need
-# them and disable mouse_escape)
-#
-# /set awl_mouse_offset <num>
-# * specifies where on the screen is the awl status bar
-#   (0 = on top/bottom, 1 = one additional line in between,
-#   e.g. prompt)
-#   you MUST set this correctly otherwise the mouse coordinates will
-#   be off
-#
-# /set mouse_scroll <num>
-# * how many lines the mouse wheel scrolls
-#
-# /set mouse_escape <num>
-# * seconds to disable the mouse, when not clicked on the windowlist
-#
-
-# Commands
-# ========
-# /awl detach <num>
-# * hide the current window from the window list. num specifies the
-#   data_level (optional)
-#
-# /awl attach
-# * unhide the current window from the window list
-#
-# /awl ack
-# * change to the next window with activity, ignoring detached windows
-#
-# /awl redraw
-# * redraws the windowlist. There may be occasions where the
-#   windowlist can get destroyed so you can use this command to
-#   force a redraw.
-#
-# /awl restart
-# * restart the connection to the viewer script.
-
-# Viewer script
-# =============
-# When run from the command line, adv_windowlist acts as the viewer
-# script to be used together with the irssi script to display the
-# window list in a sidebar/terminal of its own.
-#
-# One optional parameter is accepted, the awl_path
-#
-# The viewer can be configured by three environment variables:
-#
-# AWL_HI9=1
-# * interpret %9 as high-intensity toggle instead of bold. This had
-#   been the default prior to version 0.9b8
-#
-# AWL_AUTOFOCUS=0
-# * disable auto-focus behaviour when activating a window
-#
-# AWL_NOTITLE=1
-# * disable the title bar
