+                             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).
