+# Powershell script for cleaning up remaining browser and selenium server processes on the CI servers
+#
+# Author: Martin Stockhammer <martin_s@apache.org>  
+# Date  : 2017-04-30
+#
+# Descriptions:
+#  Stopps processes related to the selenium checks, if they were not stopped by the selenium server, because
+#  the job was aborted.
+#  The script cannot determine, which of the processes are started by the current job, so if there are
+#  parallel jobs running on this server that start processes with the same name and user, these
+#  will be stopped too.
+#
+#  Per default the script will stop "firefox.exe","iexplore.exe","chrome.exe"
+#  and the processes "java.exe","mshta.exe" if their commandline arguments contain "selenium-server"
+# 
+# Parameters:
+#  -Verbose              : If set, more output will be printed
+#  -Browsers proc1,proc2 : The list of executables that define the browser processes, that are started by selenium
+#  -SeleniumProcesses    : The list of processes with the string "selenium-server" in the commandline arguments
