			    PYBOOTCHARTGUI
			   ----------------

pybootchartgui is a tool for visualization and analysis of the
GNU/Linux boot process. It renders the output of the boot-logger tool
bootchart (see http://www.bootchart.org/) to either the screen or
files of various formats. Bootchart collects information about the
processes, their dependencies, and resource consumption during boot of
a GNU/Linux system. The pybootchartgui tools visualizes the process
tree and overall resource utilization.

pybootchartgui is a port of the visualization part of bootchart from
Java to Python and Cairo.

Adapted from the bootchart-documentation:

  The CPU and disk statistics are used to render stacked area and line
  charts. The process information is used to create a Gantt chart
  showing process dependency, states and CPU usage.

  A typical boot sequence consists of several hundred processes. Since
  it is difficult to visualize such amount of data in a comprehensible
  way, tree pruning is utilized. Idle background processes and
  short-lived processes are removed. Similar processes running in
  parallel are also merged together.

  Finally, the performance and dependency charts are rendered as a
  single image to either the screen or in PNG, PDF or SVG format.
