1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provi-
ded 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 License and to the absence of any warranty; and give any other
recipients of the Program a copy of this License alongand you may at your option offer warranty protection in ex-
change for a fee.
2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program,
and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all
of these conditions:
a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any
change.
b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Pro-
gram or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License.
c) If the modified program normally reads commands interactively when run, you must cause it, when started running
for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copy-
right notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redis-
tribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the
Program itself is interactive but does not normally print such an announcement, your work based on the Program is not
required to print an announcement.)
These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the
Program, and can be reasonably considered independent and separate works in themselves, then this License, and its
terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same
sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regard-
less of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely
by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the
Program.
In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on
the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this
License.
3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form
under the terms of Sections 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 Sections 1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete machine-readable copy of the corresponding source co-
de, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software inter-
change; or,
c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alter-
native is allowed only for noncommercial distribution and only if you received the program in object code or executab-
le form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form
of the work for making modifications to it. For an executable work, complete source code means all the source code
for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation
and installation of the executable. However, as a special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and
so on) of the operating system on which the executable runs, unless that component itself accompanies the executab-
le. If distribution of executable or object code is made by offering access to copy from a designated place, then offe-
ring equivalent access to copy the source code from the same place counts as distribution of the source code, even
though third parties are not compelled to copy the source along with the object code.
