       drgeo - a GTK+ interactive geometry program


       drgeo [OPTIONS]...


       Dr. Geo is the OFSET’s interactive geometry program.

       It  is  a  sort  of  vector  drawing  software  but  with  mathematical
       constraints - we also call this interactive geometry.

       It  allows  one  to  create  geometric  figure  plus  the   interactive
       manipulation   of   such   figure   in  respect  with  their  geometric
       constraints. It is useable in teaching  situation  with  students  from
       primary or secondary level.

       To find more information concerning the use of Dr. Geo, you can consult
       the online help.


       This program follows the usual  GNU  command  line  syntax,  with  long
       options starting with two dashes (‘--’).
