"""This is an example plugin for sos. Plugins gather, analyze, and report on various aspects
of system operation that are of interest. plugins are based on the PluginBase class, which
you should inspect if you wish to override any methods in your plugin. The methods of use
to plugin developers are:
collect() - use the functions sosCp and sosRunExe to gether information
analyze() - perform any special analysis you require beyond just saving the
information gathered by collect(). Use sosAlert() and sosAddCustomText()
to add information to the report.
report() - override this method if you wish to replace the default reporting
All plugins will use collect(), some will use analyze(), few will override report()
