27semblance of artistic control over the development of the package,
28while giving the users of the package the right to use and distribute
29the Package in a more-or-less customary fashion, plus the right to make
30reasonable modifications.

156You may charge a reasonable copying fee for any distribution of this
157Package. You may charge any fee you choose for support of this
158Package. You may not charge a fee for this Package itself. However,
159you may distribute this Package in aggregate with other (possibly
160commercial) programs as part of a larger (possibly commercial) software
161distribution provided that you do not advertise this Package as a
162product of your own. You may embed this Package's interpreter within
163an executable of yours (by linking); this shall be construed as a mere
164form of aggregation, provided that the complete Standard Version of the
165interpreter is so embedded.
166
9c9c2da3 167=item 6.
2a551100 168
169The scripts and library files supplied as input to or produced as
170output from the programs of this Package do not automatically fall
171under the copyright of this Package, but belong to whoever generated
172them, and may be sold commercially, and may be aggregated with this
173Package. If such scripts or library files are aggregated with this
174Package via the so-called "undump" or "unexec" methods of producing a
175binary executable image, then distribution of such an image shall
176neither be construed as a distribution of this Package nor shall it
177fall under the restrictions of Paragraphs 3 and 4, provided that you do
178not represent such an executable image as a Standard Version of this
179Package.
180
9c9c2da3 181=item 7.
2a551100 182
183C subroutines (or comparably compiled subroutines in other
184languages) supplied by you and linked into this Package in order to
185emulate subroutines and variables of the language defined by this
186Package shall not be considered part of this Package, but are the
187equivalent of input as in Paragraph 6, provided these subroutines do
188not change the language in any way that would cause it to fail the
189regression tests for the language.
190
9c9c2da3 191=item 8.
2a551100 192
193Aggregation of this Package with a commercial distribution is always
194permitted provided that the use of this Package is embedded; that is,
195when no overt attempt is made to make this Package's interfaces visible
196to the end user of the commercial distribution. Such use shall not be
197construed as a distribution of this Package.
