-# 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
