\subsection{Additional Permissions}
% FIXME: rework and fix formatting.

Copyleft licensing theorists have generally called

issues; in particular, additional requirements, if allowed without careful

principles in the background, section 7 answers the following questions: (1)

\begin{enumerate}
\item How do the presence of additional terms on all or part of a GPL'd program
affect users' rights?
\item When and how may a licensee add terms to code being
distributed under the GPL?
\item When may a licensee remove additional terms?
