This is a early release of ppdview, a ggi based pengaru performance datalog viewer.

This program is compiled for glibc2 based x86 linux and depends on libggi/libgii and
libttf.
It uses 1024x768 and loads a .ppd file passed as an argument.

The program also uses 256 colors so if you try to run it in X, set GGI_DISPLAY to
palemu, this will drastically hurt performance but it lets you run it in a X window.
I recommend running it on svgalib or fb where it can get a native 256 color mode on
the hardware resulting in much much better performance.

Some notes on using the program:

keys:

n		new window (new window is automatically focused)
d		delete focused window
space		cycle focused window (nothing indicates which is focused right now)
shift-space	cycle focused window in opposte direction of space (see above line)
k		show/hide the key
n<enter>	n is the number identifying a stream in the key, it will add the
		stream to the focused window, or if the stream is already in the
		focused window it will remove it.  The first two streams added to
		a window get the left then right scales, any additional streams
		added are scale-less.
q		quits
left		goes back in time (til start of log file is reached)
right		goes forward in time (til end of log file is reached)
up		increases # of seconds displayed (up to 60 seconds right now)
down		decreases # of seconds displayed (down to 1 second)
ctrl-left	moves info line back in time
ctrl-right	moves info line forward in time
home		brings info line into the viewed region
		In this release the info line does not display any info, it will
		when finished show the values of the streams where the line
		intersects the streams, similar to how the dynojet / winpep software
		shows hp/tq values where the intersections are with a similar
		vertical line you can move along the X axis.
n<left_shift>	assigns n data streams scale to the left scale of the focused window
n<right_shift>	assigns n data streams scale to the right scale of the focused window
		these last two commands are unimplemented and really I'm undecided on
		including them, it would be nice to have a way for assigning the
		scales if you've assigned more than two streams to a window... 



When you start the program it will have no windows created and a key visible, before
you can assign streams to be shown you must create a window, so hit 'n'.  Now you
have a window, now enter the # of a stream you want to see e.g.  0<enter> to see
stream 0 on the new window.  Now, if you want to put a second stream on this window
hit another # then <enter>.  If you enter the same number the last stream you added
will disappear (toggles on/off).  Note that you must hit enter before the # is
processed.  You may assign the same streams to multiple windows if you wish.

Invoke the program like so:  ./ppdview ppd_file_name
with the font.ttf file in the current working directory.  The provided font.ttf file
is Sans from bitstream, you may replace it with any other standard ttf file if you
like.
