OPTIONS: Default\n\
-i <input image path> %s\n\
Set image input path.\n\
From this path read \"Klimt/Klimt.pgm\"\n\

Setting the VISP_INPUT_IMAGE_PATH environment\n\
variable produces the same behaviour than using\n\
this option.\n\
\n\
-o <output image path> %s\n\
Set image output path.\n\
From this directory, creates the \"%s\"\n\
subdirectory depending on the username, where \n\
Klimt_grey.overlay.ppm output image is written.\n\
\n\
-c\n\
Disable the mouse click. Useful to automate the \n\
execution of this program without humain intervention.\n\
\n\
-d \n\
Disable the image display. This can be useful \n\
for automatic tests using crontab under Unix or \n\
using the task manager under Windows.\n\

-h\n\
Print the help.\n\n", ipath.c_str(), opath.c_str(), user.c_str());
