0.1.1-win5
   + installs on BOTH scilab 2.6 and 2.7
   + help system now works with scilab 2.7 (and 2.6 also)

0.1.1-win4
   + imshow now does a refresh on the current window. This fixes
   the problem that made images be invisible under Windows.

0.1.1 
   + "gsm" function got better but compatible. The user may
   select if input or output is in time (real), complex
   or frequency, enabling more effective use of FFT's.
   + "fftderiv" now enables input to be in time (real),
   complex or frequency. It also has a sigma parameter for
   simultaneous gaussian smoothing. This is an incompatible
   change.  
   + "curvature" is 2x faster.
   + many manpage fixes 
   + various minor fixes

0.1 Initial release
   + I/O of image files in almost ANY format, using
   ImageMagick 5.4.2
   + display is done using scilab's own graphical window.
   + new functions with flexible, stable interface and 
   error treatment.
   + stable interfaces and error treatment in the
   previous functions
   + help pages for all the functions, with EXAMPLES
   sections.
   + demos
   + home page
   + nice photographs (thanks to Eduardo Justiniano)

0.0 FABBRI toolbox
   the ancestor of the SIP toolbox. Did very simple
   image processing, without well-defined interfaces
   for the functions. Almost no documentation. Had to
   rely on IMAGE toolbox to read in just PPM/PGM/PBM
   ascii image files and display with an external program.
