TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

- Program or a portion of it, either verbatim or with modifications. Each
- licensee is addressed as "you".
-
- 1. You may copy and distribute verbatim copies of the Program's source
- code as you receive it, in any medium, provided that you conspicuously and
- appropriately publish on each copy an appropriate copyright notice and
- disclaimer of warranty; keep intact all the notices that refer to this
- General Public License and to the absence of any warranty; and give any
- other recipients of the Program a copy of this General Public License
- along with the Program. You may charge a fee for the physical act of
- transferring a copy.
-
- 2. You may modify your copy or copies of the Program or any portion of
- it, and copy and distribute such modifications under the terms of Paragraph

- with or without modifications, to be licensed at no charge to all
- third parties under the terms of this General Public License (except
- that you may choose to grant warranty protection to some or all
- third parties, at your option).
-
- c) If the modified program normally reads commands interactively when
- run, you must cause it, when started running for such interactive use
- in the simplest and most usual way, to print or display an
- announcement including an appropriate copyright notice and a notice
- that there is no warranty (or else, saying that you provide a
- warranty) and that users may redistribute the program under these
- conditions, and telling the user how to view a copy of this General

If you develop a new program, and you want it to be of the greatest
possible use to humanity, the best way to achieve this is to make it
free software which everyone can redistribute and change under these
terms.
- To do so, attach the following notices to the program. It is safest to
- attach them to the start of each source file to most effectively convey
- the exclusion of warranty; and each file should have at least the
- "copyright" line and a pointer to where the full notice is found.
