Matplotlib strives to produce publication quality 2D graphics for
interactive graphing, scientific publishing, user interface development
and web application servers targeting multiple user interfaces and
hardcopy output formats.  The 'pylab' mode of ipython uses matplotlib
to emulate matlab graphics.

OPTIONAL DEPENDENCIES: pytest, mock, ffmpeg/avconv, Inkscape,
                       wxPython3

NOTES: The optional wxagg backend is disabled by default because
       of possible issues related to wxPython versions. If you wish to
       use this backend install wxPython3 in advance and set
       DISABLE_WXAGG to "no" when executing the SlackBuild.

       IMPORTANT: There is some interaction between wxPython and
                  wxPython3, pay attention to the corresponding
                  README files.

       If you want to enable the optional subpackages tests and
       toolkits_tests you need to set the variable ENABLE_TESTS to
       "yes" when executing the SlackBuild and make sure that pytest,
       mock, ffmpeg/avconv and Inkscape are already installed. Besides
       ffmpeg/avconv are also needed if you wish better support of
       animation output formats.

       Version 2.2.5 is the last available for python2.
