Revision history for Perl extension PDL::Graphics::PLPLOT

0.01  1/23/2002
	- original version

0.11  First version released to CPAN.  Does line and point plots and Shade plots.
      Still missing support for 3D plots (but this could easily be added).

0.19  1/31/2003 First version integrated into the PDL distribution.  Includes
      Support for 'mem' driver for in-memory plotting on top of RGB images.

0.20  7/16/2003 Broke package apart from main PDL distribution to allow separate development.
      Now package should work either as part of PDL distro (with plplot.t moved to PDL/t directory)
      or independently (with plplot.t in PDL-Graphics-PLplot/t directory).
      Added controls for tick size, tick spacing and error bars.

0.21  11/21/2003 Fixed test suite to use Test::More, updated to work with plplot-5.2.1.
      Back-ported to main PDL distro.
