This library is supposed to help you to make plots as if you were using Matlab.
Since version 0.43, the naming convention of plotlib functions has changed :
underscores are no longer used and plotlib functions take precedence over
original Scilab functions (like plot, gca, gcf, surf, ...) at loading time.
Version 0.45 fixes various bugs and suppresses (almost) all plotlib global
variables.
