    # ########################################################################
    # A script to summarize system information in a nice way.
    # Goals: work well on Linux; create a compact diff-able report that is
    # easy to paste into a wiki or email, and easy to scan and compare too.
    #
    # Usage: $ wget -O- http://aspersa.googlecode.com/svn/trunk/summary |bash
    # Options are set through the ASPERSA_SKIP environment variable.  Set this
    # variable to a comma-separated list of things you want to omit.
    # Options:
    #  MOUNT:   Don't print out mounted filesystems and disk fullness.
    #  NETWORK: Don't print out information on network controllers & config.
    #  PROCESS: Don't print out top processes and vmstat information.

    # so on, until it finds a number that's large enough.  The pattern is slightly
