“Draw is probably the most under-estimated of the OpenOffice.org
applications. Either users seem to expect it to be equivalent to
the GIMP or Visio, or they fail to see its desktop publishing

and almost all seem to still be in heavy development.“Like most OpenOffice.org extensions, those for Draw are
installed via Tools -> Extension Manager. Usually, the easiest
way to install them is by selecting My Extensions, and readying
them for the current account only. Many of the extensions are
written in Java, although a free implementation like IcedTea or GCJ
is usually all that is necessary, rather than a copy of Sun’s
