* used in commercial products. Because of this, I am willing to
* consider alternate license arrangements as allowed in Section 10 of
* the GNU GPL. Before I would consider licensing tcptrace under an
* alternate agreement with a particular individual or company,
* however, I would have to be convinced that such an alternative
* would be to the greater benefit of the networking community.
