Make a grid in any shape and size from mini to jumbo, rectangular,
hex or circular, on a Moebius strip or on a torus... and much more.
Use bars or blocks - or even a mixture of both.
Dozens of types of symmetry including simple rotational symmetry and
mirror symmetries as well as 'left-and-right' and 'up-and-down'.
Interactive or fully automatic filling of whole or partial grid.

NOTE:  If you wish to include the qxw-guide.[version].pdf in the package,
download from http://www.quinapalus.com/qxw.html and add
the file to your Qxw SlackBuild directory (where this file is).
