This is version 2.1 of xdl, a program to display DL animations in an X
window. The first version, which was really just a quick hack (well
this version still is...), was limited in many ways and some of those
limitations should be gone in with this release.

No, I have no idea where you might find any DL-files, sorry!


New features in 2.1:

 - Faster startup due to my own bit-fiddlings instead of
   numerous calls to XPutPixel.

 - New switches -v, for verbose, to make the program tell you what it
   thinks it's doing (default is now silent) and -d <display> to
   specify the X display to connect to.

 - Several files can be specified on the command line.

 - The program understands some events when it is running. Pressing
   'n' or <space> or the left mousebutton start the animation of the 
   next file given on the commandline. Pressing 'q' or the right 
   mousebutton exits the program.

 - Hopefully the use of the timer is slightly more portable then before...


New features in 2.0:

 - It can now run on almost any display running X-windows. I have
   tested it on monochrome, 8-bit and 24-bit per pixel systems whithout
   any problem.

 - Animations in the "medium" format (160x100) can be zoomed up to
   "large" format (320x200). In color it is a simple nearest neighbour,
   but in monochrome, the error distribution gives some smoothing too.

 - The user can decide how fast (frames per second) the animation should
   be displayed with a command line switch. Thanks to Per Beremark for
   this.

 - Several people complained that their systems did not have the usleep()
   call in their libraries so I changed the program to use select() to 
   get a delay instead. I hope this will make it more portable.

 - There is now a man-page and a Makefile for the program.


Installation:

Since there is now a small Makefile for the program it should be
quite easy to install. Edit the Makefile so it fits the setup at
your site and then type "make". This will compile the program.
Typing "make install" will compile the program and install it and
the man-page in the places indicated in the Makefile.

Have fun!
