This module defines the messages diplay class, and creates the application-wide
msg object.

00012 class Message (object):
    All messages in the program are output using the `msg' object in the
    main package. This class defines the interface for this object.
00017     def __init__ (self, level=1, write=None):
        Initialize the object with the specified verbosity level and an
        optional writing function. If no such function is specified, no
        message will be output until the 'write' field is changed.

        This is the low level printing function, it receives a line of text
        with an associated verbosity level, so that output can be filtered
        depending on command-line options.

        kind of message, among "error", "warning", "abort", the argument
        'text' is the main text of the message, the other arguments provide
        additional information, including the location of the error.
