+# This recipe creates packages for the bootchart2 system-wide profiler daemon 
+# and related utilities. Depending on the images you're building, additional
+# configuration may be needed in order to use it.
+#
+# Packages:
+#   *   bootchart2 - The daemon itself.
+#   *   pybootchartgui - Python program to visualize and display the data
+#       collected by bootchart2 or compatible daemons such as the original 
+#       bootchart.
+#   *   bootchartd-stop-initscript - A SysV init script to stop data collection
+#       when booting completes (see below for details.)
+#
+# While bootchart2 is designed to stop collecting data roughly when the boot 
+# process completes, it is not exactly a stopwatch. It has a list of programs 
+# which are supposed signify that the boot process has completed (for example,
+# openbox or gnome-shell,) but it waits a full 20 seconds after such a program
+# is launched before stopping itself, to collect additional data.
+#
+# If you are using a window manager or GUI which isn't included in bootchart2's
+# default configuration file, you should write bbappend file to amend
+# bootchartd.conf and add it to EXIT_PROC. An example of this is shown in this
+# recipe, where the Matchbox window manager (used by Sato) is added.
+#
+# If you want data collection to end at a certain point exactly, you should
+# arrange for the following command to be run:
+#   bootchartd stop
+# You might set this command to be launched by the desktop environment shipped
+# on the image you're building after the other startup programs are complete.
+# This will not incur the 20 second wait period and will cause bootchart2 to
+# behave a bit more like a stopwatch. An example of this is shown in this 
+# recipe, specifically the bootchartd-stop-initscript package, which stops data
+# collection as the last action when switching to runlevels 2 through 5. You can
+# add bootchartd-stop-initscript to IMAGE_INSTALL if you need to use it.
+#
+# Unless you're doing something special, if your image does not launch an X 
+# window manager, you will need to add bootchartd-stop-initscript to your image.
+#
+# Bootchart2 can be started in two ways. Data collection can be initiated by
+# running the following command:
+#   bootchartd start
+# However, for the most complete data, the bootchart2 developers recommend
+# running it as PID 1. This can be done by adding the following to the kernel 
+# command line parameters in the bootloader setup:
+#   init=/sbin/bootchartd
+# When invoked this way, bootchart2 will set itself up and then automatically 
+# run /sbin/init. For example, when booting the default qemux86 image, one might
+# use a command like this:
+#   runqemu qemux86 bootparams="initcall_debug printk.time=y quiet \
+#                               init=/sbin/bootchartd"
+#
+# Neither method is actually implemented here, choose what works for you.
+#
+# If you are building your image with systemd instead of SysV init, bootchart2
+# includes systemd service files to begin collection automatically at boot and 
+# end collection automatically 20 seconds after the boot process has completed.
+# However, be aware that systemd tends to start bootchart2 relatively late into
+# the boot process, so it's highly recommended to use bootchart2 as PID 1. If 
+# you're using systemd and you wish to use another method to stop data
+# collection at a time of your choosing, you may do so as long as you get to it
+# before the 20 second timeout of the systemd service files. Also, you may write
+# a bbappend to patch bootchart2-done.timer.in to increase or decrease the
+# timeout. Decreasing it to 0 will make it behave like
+# bootchartd-stop-initscript.
+#
+# By default, when data collection is stopped, a file named bootchart.tgz will
+# be created in /var/log. If pybootchartgui is included in your image,
+# bootchart.png will also be created at the same time. However, this results in
+# a noticeable hitch or pause at boot time, which may not be what you want on an
+# embedded device. So you may prefer to omit pybootchartgui from your image. In
+# that case, copy bootchart.tgz over to your development system and generate
+# bootchart.png there. To get pybootchartgui on your development system, you can
+# either install it directly from some other source, or build bootchart2-native
+# and find pybootchartgui in the native sysroot:
+#    bitbake bootchart2-native
+#   ./tmp/sysroots/x86_64-linux/usr/bin/pybootchartgui /path/to/bootchart.tgz
+# Note that, whether installed on your build system or on your image, the 
+# pybootchartgui provided by this recipe does not support the -i option. You 
+# will need to install pybootchartgui by other means in order to run it in
+# interactive mode.
