- GENERAL PUBLIC LICENSE TO COPY
-
- 1. You may copy and distribute verbatim copies of this source file
-as you receive it, in any medium, provided that you conspicuously and
-appropriately publish on each copy a valid copyright notice "Copyright
-(C) 1985 Free Software Foundation, Inc."; and include following the
-copyright notice a verbatim copy of the above disclaimer of warranty
-and of this License. You may charge a distribution fee for the
-physical act of transferring a copy.
-
- 2. You may modify your copy or copies of this source file or
-any portion of it, and copy and distribute such modifications under
-the terms of Paragraph 1 above, provided that you also do the following:
-
- a) cause the modified files to carry prominent notices stating
- that you changed the files and the date of any change; and
-
- b) cause the whole of any work that you distribute or publish,
- that in whole or in part contains or is a derivative of this
- program or any part thereof, to be licensed at no charge to all
- third parties on terms identical to those contained in this
- License Agreement (except that you may choose to grant more extensive
- warranty protection to some or all third parties, at your option).
-
- c) You may charge a distribution fee for the physical act of
- transferring a copy, and you may at your option offer warranty
- protection in exchange for a fee.
-
-Mere aggregation of another unrelated program with this program (or its
-derivative) on a volume of a storage or distribution medium does not bring
-the other program under the scope of these terms.
-
- 3. You may copy and distribute this program (or a portion or derivative
-of it, under Paragraph 2) in object code or executable form under the terms
-of Paragraphs 1 and 2 above provided that you also do one of the following:
-
- a) accompany it with the complete corresponding machine-readable
- source code, which must be distributed under the terms of
- Paragraphs 1 and 2 above; or,
-
- b) accompany it with a written offer, valid for at least three
- years, to give any third party free (except for a nominal
- shipping charge) a complete machine-readable copy of the
- corresponding source code, to be distributed under the terms of
- Paragraphs 1 and 2 above; or,
-
- c) accompany it with the information you received as to where the
- corresponding source code may be obtained. (This alternative is
- allowed only for noncommercial distribution and only if you
- received the program in object code or executable form alone.)
-
-For an executable file, complete source code means all the source code for
-all modules it contains; but, as a special exception, it need not include
-source code for modules which are standard libraries that accompany the
-operating system on which the executable file runs.
-
- 4. You may not copy, sublicense, distribute or transfer this program
-except as expressly provided under this License Agreement. Any attempt
-otherwise to copy, sublicense, distribute or transfer this program is void and
-your rights to use the program under this License agreement shall be
-automatically terminated. However, parties who have received computer
-software programs from you with this License Agreement will not have
-their licenses terminated so long as such parties remain in full compliance.
-
- 5. If you wish to incorporate parts of this program into other free
-programs whose distribution conditions are different, write to the Free
-Software Foundation at 675 Mass Ave, Cambridge, MA 02139. We have not yet
-worked out a simple rule that can be stated here, but we will often permit
-this. We will be guided by the two goals of preserving the free status of
-all derivatives of our free software and of promoting the sharing and reuse of
-software.
-
-
-In other words, you are welcome to use, share and improve this program.
-You are forbidden to forbid anyone else to use, share and improve
