The terms of use for StrutLayout are set by the Library GNU Public Licence, which essentially allows you to use StrutLayout in unmodified form within commercial and free software, but if you modify it in any way you must make the updated source available under the LGPL.  It also says that this software comes with no warranty, express or implied, etc, etc.  This means that you probably shouldn't use it in nuclear power plants or oil-tanker navigation systems. 

OK, legal incantations out of the way, download StrutLayout from the link below.  Gunzip and untar and then look at the README for more information on using StrutLayout.   The javadoc documentation (read online) is inluded in the package.
