COPYING CONDITIONS FOR CTAN SNAPSHOT:

A snapshot of the Comprehensive TeX Archive Network (CTAN) holdings is
taken from time to time and distributed on physical media.  It may be
bundled with the TeX Live system, or distributed separately.

In any case, the licensing conditions of the packages in the CTAN
snapshot vary widely.  In particular (and in contrast to TeX Live), not
all the software meets free software or open source criteria: some are
available only as binaries, others have restrictions on commercial
resale, and so on.

Thus, when redistributing the CTAN snapshot, you must be very careful
that you are not violating any license conditions.  Since each situation
is different, we cannot offer any general advice.

To learn redistribution requirements, of course the licensing
information within the packages themselves is the final authority. For
summary information, we suggest checking the package pages
at http://ctan.org/pkg.

If you believe any files have been included erroneously, please contact
us (references are given below).

If you have any questions or comments, feel free to contact us.  
Thanks for your interest in TeX.
