# This program is a simple interactive shell for VirtualBox. You can query      #
# information and issue commands from a simple command line.                    #
#                                                                               #
# It also provides you with examples on how to use VirtualBox's Python API.     #
# This shell is even somewhat documented, supports TAB-completion and           #
# history if you have Python readline installed.                                #
#                                                                               #
# Finally, shell allows arbitrary custom extensions, just create                #
# .VirtualBox/shexts/ and drop your extensions there.                           #
#                                                Enjoy.                         #
