Appendix E Open Source Licences
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.
A compilation of a covered work with other separate and independent works,
which are not by their nature extensions of the covered work, and which are not
combined with it such as to form a larger program, in or on a volume of a storage
or distribution medium, is called an "aggregate" if the compilation and its resulting
copyright are not used to limit the access or legal rights of the compilation's users
beyond what the individual works permit. Inclusion of a covered work in an
aggregate does not cause this License to apply to the other parts of the
aggregate.
