%% Package `multicol' to use with LaTeX2e
%% Copyright (C) 1989-1996 Frank Mittelbach, all rights reserved.
%%
%%
%% In addition to the general distribution terms for this `tools'
%% bundle, which are specified in readme.txt, this package, multicol,
%% is distributed subject to the following condition:
%%
%% ** The use of this package as part of a commercial application is
%% ** not allowed without the explicit permission of the author of
%% ** this package. Such commercial usage will be subject to the
%% ** payment of a license fee. The size of this fee is to be
%% ** determined, in each instance, by the commercial user, depending
%% ** on his judgment of the value of the code for his application.
%%
%%
%% Note that the above condition does not apply to non-commercial use
%% of this package, or to the use of this package in a commercial
%% environment for `private' tasks rather than as part of a commercial
%% application. In these cases the General Terms, as specified in
%% readme.txt, apply.
%%
%% The term `private' tasks in a commercial environment refers to the
%% use of multicol to format documents received by others, for example,
%% to format the documentation of a package which often uses multicol
%% internally. It also refers to the generation of documents that are
%% intended to be available free of charge. It does not refer to the
%% act of producing a commercial product, eg, a book or a
%% journal. Such usage require a license fee.
%% In that case please send email to
%%
%% Frank.Mittelbach@Uni-Mainz.de
