If you want to use files covered by this License Agreement in yourown software, that shouldn't be any problem, but we recommend thatyou also include a full copy of its text. Some of the files containalternative license terms which are nonfree, or no licensinginformation at all, so including a copy of the License Agreementwill help avoid confusion when others want to distribute yoursoftware. Of course, you'll also need to follow the conditions inthis License Agreement for distributing the files, but those arevery straightforward.
Please take care to ensure that the files you are using are coveredby this License Agreement.
