Conveying under any other circumstances is permitted solely under the conditions
stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological measure under
any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty
adopted on 20 December 1996, or similar laws prohibiting or restricting
circumvention of such measures.
When you convey a covered work, you waive any legal power to forbid circumvention
of technological measures to the extent such circumvention is effected by exercising
rights under this License with respect to the covered work, and you disclaim any
intention to limit operation or modification of the work as a means of enforcing,
against the work's users, your or third parties' legal rights to forbid circumvention of
technological measures.
4. Conveying Verbatim Copies.
You may convey 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; keep intact all notices stating that this License
and any non-permissive terms added in accord with section 7 apply to the code; keep
intact all notices of the absence of any warranty; and give all recipients a copy of this
License along with the Program.
You may charge any price or no price for each copy that you convey, and you may
offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to produce it
from the Program, in the form of source code under the terms of section 4, provided
that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified it, and giving a
relevant date.
b) The work must carry prominent notices stating that it is released under this
License and any conditions added under section 7. This requirement modifies the
requirement in section 4 to 'keep intact all notices'.
