+# INFO
+###
+#
+#  Currently running on Linux, OpenBsd and FreeBsd.
+#
+#  Type this to add the item:
+#
+#    /statusbar window add nact
+#
+#  See
+#  
+#    /help statusbar
+#
+#  for more help on how to custimize your statusbar.
+#  Add something like this to your theme file to customize to look of the item
+#
+#    nact_display = "$0%R>%n%_$1%_%G>%n$2";
+#    
+#  where $0 is the input, $1 the device and $2 the output. To customize the
+#  outout of the /bw command add something like
+#
+#    nact_command = "$0)in:$1:out($2";
+#
+#  to your theme file.

+##########
+# THEME
+####
+#
+# This is the complete list of parameters passed to the format:
+#
+#    $0: incomming rate
+#    $1: name of the device, eg. eth0
+#    $2: outgoing rate
+#    $3: total bytes received
+#    $4: total bytes sent
+#    $5: sum of $4 and $5
+#
+#########
+# TODO
+###
+#
+# Make this script work on other unices, For that i need some infos on where
+# to find the total amount of sent bytes on other systems. You may be so kind
+# as to send me the name of such a file and a sample output of it.
+#
+#   or
+#
+# you can be so kind as to send me a patch. Fort that _please_ check that you
+# do have the latest nact.pl and use these diff switches:
+#
+#   diff -uN nact.pl.new nact.pl.old 
+#
+############
+# OPTIONS
+######
+#
+# /set nact_command <command>
+#   command: command to execute on /bw. example:
+#
+#     /set nact_command /say
+#
+# /set nact_devices <devices>
+#   devices: space seperated list of devices to display
+#
+# /set nact_interval <n>
+#   n: number of mili-seconds to wait before an update of the item
+#
+# /set nact_format <format>
+#   format: a format string like the one with sprintf. examples: 
+#
+#     /set nact_format %d    no digits after the point at all
+#     /set nact_format %.3f  3 digits after the point
+#     /set nact_format %.5f  5 digits after the point
+# 
+# /set nact_unit <n>
+#   n: set the unit to KiB, MiB, or GiB. examples:
+#
+#     /set nact_unit 0 calculate dynamically
+#     /set nact_unit 1 set to KiB/s
+#     /set nact_unit 2 set to MiB/s
+#     /set nact_unit 3 set to GiB/s
