     #       Master machine independent configuration file.
    #
    #       Specific configuration files are created based on this and
    #       the machine specific master file using the doconf script.
    #
    #       Any changes to the master configuration files will affect all
    #       other configuration files based upon it.
    #
    #######################################################################
    #
    #       To build a configuration, execute "doconf <configuration>."
    #       Configurations are specified in the "Configurations:" section
    #       of the MASTER and MASTER.* files as follows:
    #
    #       <configuration> = [ <attribute0> <attribute1> ... <attributeN> ]
    #
    #       Lines in the MASTER and MASTER.* files are selected based on
    #       the attribute selector list, found in a comment at the end of
    #       the line.  This is a list of attributes separated by commas.
    #       The "!" operator selects the line if none of the attributes are
    #       specified.
    #
    #       For example:
    #
    #       <foo,bar>       selects a line if "foo" or "bar" are specified.
    #       <!foo,bar>      selects a line if neither "foo" nor "bar" is
    #                       specified.
    #
    #       Lines with no attributes specified are selected for all
    #       configurations.
    #
