The cva-input program demonstrates the XTest section of libcvautomation.\n\

Usage: \n\
\n\
\t-h, --help:\t\tDisplay this usage message.\n\
\t-u, --usage:\t\tDisplay this usage message.\n\
\t-d, --display:\t\tSpecify the X display to use.\n\
\t-m, --search-method:\tSpecify a method to search by. See `cva-match --help\'\n\
\t\t\t\tfor more information on this.\n\
\t-t, --tolerance:\tSpecify how strict the match is.\n\
\t-b, --button:\t\tSpecify the mouse button to press (default 1).\n\
\t-c, --center:\t\tInstead of matching the top-left corner of an image,\n\
\t\t\t\tmatch the center of the image.\n\
\t-s, --string:\t\tCommand string - see below.\n\
\n\
This program works kind of like a mini-language. All options\n\
are parsed left-to-right, and executed right there. Thus, specifying \"--display\"\n\
at different places in the options will cause this program to use the most recent\n\
given display.\n\
Available commands:\n\
\tmouseclick:\tClick the mouse in-place.\n\
\timouseclick:\tClick the mouse at an image's top-left corner.\n\
\ticmouseclick:\tClick the mouse at an image's center.\n\
\tmousexy:\tMove the mouse to the given coordinate.\n\
\tmouserxy:\tMove the mouse by the given x and y values (relative motion).\n\
\tmouseimage:\tMove the mouse to an image's top-left corner.\n\
\tcmouseimage:\tMove the mouse to an image's center.\n\
\tmousedown:\tPush and leave down a mouse button.\n\
\tmouseup:\tRelease a mouse button.\n\
\tmousejiggle:\tJiggle the mouse (helps to activate some widgets).\n\
\tkeyclick:\tClick a keyboard button.\n\
\tkeydown:\tPush and leave down a keyboard button.\n\
