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”.
c) You must license the entire work, as a whole, under this License to anyone who comes
into possession of a copy. This License will therefore apply, along with any applicable
section 7 additional terms, to the whole of the work, and all its parts, regardless of how they
are packaged. This License gives no permission to license the work in any other way, but it
does not invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display Appropriate Legal Notices;
however, if the Program has interactive interfaces that do not display Appropriate Legal
Notices, your work need not make them do so.
