This is just a basic tool, which provides a means of measuring distance

between any two points on the screen. Currently, the distances are shown

in pixels, millimeters, and inches.

To use this, set your PATH to the appropriate directory, and issue the

command:

     xmruler &

To measure any distance:

  1. click on "Measure" button. The shell is unmapped, the pointer is grabbed,

     and the cursor changes to "cross".

  2. Select the first point by clicking MB1. As soon as you select the 

     first point, the cursor changes to "reverse cross", and the grab is 

     still on. (This will be eventually changed to a rubberbanding cursor).

  3. Select the second point. The pointer is ungrabbed, the shell remapped,

     and the distances (both height and width on the screen) are displayed

     in pixels, millimeters, and inches.

  4. You can either quit by selecting Quit, or keep the ruler around by

     iconifying it.
