[tex-live] License of lamsarrow.sty

Dear Michael,

we from the TeX Live Team have found that the file lamsarrow.sty
shipping in the pb-diagram package on CTAN  seems to be undistributable
in TeX Live, and has root in your LamS-TeX:

% lamsarrow.sty: fancy arrows using lams fonts
% Author: extracted from Michael Spivak's LamS-TeX by Paul Burchard
% Version Number: 4.1
% Version Date: 24 Jan 1997
%--------------------- LamS-TeX copyright -------------------------
% COPYRIGHT (C) 1989, 1990, 1991 by the Texplorators Corporation,
% 1572 West Gray #377, Houston, TX 77019-4948 (ALL RIGHTS RESERVED)

I am not sure whether Texplorators Corporation still exists, but since
it seems that you are the main author we would like to ask whether you
confirm that licensing issue (ALL RIGHTS RESERVED), in which case we
have to remove it from TeX Live, or if you would be so kind and
re-license it to some open license (e.g., LPPL).

Thanks a lot and all the best

SHIFNAL (n.,vb.)
An awkward shuffling walk caused by two or more people in a hurry
accidentally getting into the same segment of revolving door. A
similar effect is achieved by people entering three-legged races
unwisely joined at the neck instead of the ankles.
