The copyright for the files and changes needed for the Unicode
support was indeed transferred to CNRI earlier this year. This
was part of the contract I had with CNRI.
I don't know why the copyright notice wasn't subsequently removed from
the files after final checkin of the changes, though, because, as
I remember, the copyright line was only added as "search&replace"
token to the files in question in the sign over period.
The codec files were part of the Unicode support patch, even though
they were created by the gencodec.py tool I wrote to create them
from the Unicode mapping files. That's why they also carry the
Note that with strict reading of the CNRI license, there's no
problem with removing the notice from the files in question:
...provided, however, that CNRI's
License Agreement and CNRI's notice of copyright, i.e., "Copyright (c)
1995-2000 Corporation for National Research Initiatives; All Rights
Reserved" are retained in Python 1.6 alone or in any derivative
version prepared by Licensee...
The copyright line in the Unicode files is
"(c) Copyright CNRI, All Rights Reserved. NO WARRANTY.", so this
does not match the definition they gave in their license text.
