tions 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 perfor-
ming source distribution, a complete machine-readable copy of the cor-
responding source code, to be distributed under the terms of Sections 1
and 2 above on a medium customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer to dis-
tribute corresponding source code. (This alternative is allowed only for
noncommercial distribution and only if you received the program in ob-
ject code or executable form with such an offer, in accord with Subsec-
tion b above.)
The source code for a work means the preferred form of the work for ma-
king 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 sour-
ce code distributed need not include anything that is normally distribut-
ed (in either source or binary form) with the major components (compi-
ler, kernel, and so on) of the operating system on which the executable
runs, unless that component itself accompanies the executable.
If distribution of executable or object code is made by offering access to
copy from a designated place, then offering equivalent access to copy
the source code from the same place counts as distribution of the sour-
ce code, even though third parties are not compelled to copy the source
along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program ex-
cept as expressly provided under this License. Any attempt otherwise to
copy, modify, sublicense or distribute the Program is void, and will auto-
matically terminate your rights under this License. However, parties who
have received copies, or rights, from you under this License will not have
their licenses terminated so long as such parties remain in full compli-
ance.
5. You are not required to accept this License, since you have not signed
it. However, nothing else grants you permission to modify or distribute
