2 Basic Permissions.
All rights granted under this License
are granted for the term of copyright
on the Program, and are irrevocable
provided the stated conditions are
met. This License explicitly affirms
your unlimited permission to run the
unmodified Program. The output from
running a covered work is covered by
this License only if the output, given
its content, constitutes a covered
work. This License acknowledges your
rights of fair use or other
equivalent, as provided by copyright
law.
You may make, run and propagate
covered works that you do not convey,
without conditions so long as your
license otherwise remains in force.
You may convey covered works to others
for the sole purpose of having them
make modifications exclusively for
you, or provide you with facilities
for running those works, provided that
you comply with the terms of this
License in conveying all material for
which you do not control copyright.
Those thus making or running the
covered works for you must do so
exclusively on your behalf, under your
direction and control, on terms that
prohibit them from making any copies
of your copyrighted material outside
their relationship with you.
Conveying under any other
circumstances is permitted solely
under the conditions stated below.
Sublicensing is not allowed; section
10 makes it unnecessary.
