-                             Qwt License
-                      Version 1.0, January 1, 2003
-The Qwt library and included programs are provided under the terms
-of the GNU LESSER GENERAL PUBLIC LICENSE (LGPL) with the following
-exceptions:
-    1. Widgets that are subclassed from Qwt widgets do not
-       constitute a derivative work.
-    2. Static linking of applications and widgets to the
-       Qwt library does not constitute a derivative work
-       and does not require the author to provide source
-       code for the application or widget, use the shared
-       Qwt libraries, or link their applications or
-       widgets against a user-supplied version of Qwt.
-       If you link the application or widget to a modified
-       version of Qwt, then the changes to Qwt must be 
-       provided under the terms of the LGPL in sections
-       1, 2, and 4.
-    3. You do not have to provide a copy of the Qwt license
-       with programs that are linked to the Qwt library, nor
-       do you have to identify the Qwt license in your
-       program or documentation as required by section 6
-       of the LGPL.
-       However, programs must still identify their use of Qwt.
-       The following example statement can be included in user
-       documentation to satisfy this requirement:
-           [program/widget] is based in part on the work of
-           the Qwt project (http://qwt.sf.net).
