|
90 Standard Version, under the Original License, so that the Copyright Holder |
|
91 may include your modifications in the Standard Version. |

94 Version must bear a name that is different from the name of the Standard |
|
95 Version. |

111 while you are carrying out such distribution, become invalid, you must |
|
112 provide new instructions on demand or cease further distribution. If |
|
113 you provide valid instructions or cease distribution within thirty days |

119 Source of the Modified Version. Aggregating or Linking the Package |
|
120 |
|
121 (7) You may aggregate the Package (either the Standard Version or |
|
122 Modified Version) with other packages and Distribute the resulting |
|
123 aggregation provided that you do not charge a licensing fee for the |
|
124 Package. Distributor Fees are permitted, and licensing fees for other |
|
125 components in the aggregation are permitted. The terms of this license |

|
127 as included in the aggregation. |
|
128 |
|
129 (8) You are permitted to link Modified and Standard Versions with other |
|
130 works, to embed the Package in a larger work of your own, or to build |
|
131 stand-alone binary or bytecode versions of applications that include the |
|
132 Package, and Distribute the result without restriction, provided the |
|
133 result does not expose a direct interface to the Package. Items That |
|
134 are Not Considered Part of a Modified Version |
|
135 |
|
136 (9) Works (including, but not limited to, modules and scripts) that |
|
137 merely extend or make use of the Package, do not, by themselves, cause |
|
138 the Package to be a Modified Version. In addition, such works are not |
|
139 considered parts of the Package itself, and are not subject to the terms |
|
140 of this license. General Provisions |
