Re: a simpler logger [?]

[Andrew Cagney <cagney at redhat dot com>]

FYI,

Much of frysk-sys is now using this logger; in switching my stack-smash 
bug seems to have gone back into hiding, sigh :-(

In using this logger, I've also made the following refinements:

-> The option is renamed to << -debug <what> >> rather than << -trace 
<what> >>; "trace" gets confusing when using tools such as ftrace (I'm 
not sure that -debug is much better though :-)

-> The option parser is far more (far too?) forgiving in what it 
accepts; for instance:
    -debug frysk.expunit                          -- default to level FINE
    -debug frysk.expunit=FINEST         -- explicit
    -debug FINE                                        -- global

-> The logger understands class inheritance - explicitly setting a super 
classes log-level automatically updates all sub-classes; for instance:
    -debug frysk.junit.TestCase             -- enables logging for all 
instances of TestCase including sub-classes.
