%% This is file `nomulticol.sty',
%% a tweak in package multicol.sty [2000/07/10 v1.5z multicolumn formatting (FMi)]
%% Tweaked by Dirk Roorda 2003/01/09
%%
%% purpose: to have the \begin{multicols} \end{multicols} functionality without
%% putting the material inside a group
%%
%% reason: in PassiveTeX a fo:flow is embedded in a multicols environment.
%% But the fo:block span="all" must be able to interrupt this.
%% However, sayin \end{multicols} just before and \begin{multicols}{N} just after
%% does not work, because it makes the attributes, set between the start of the flow
%% and the beginning of the block, invisible.
%% That's why a grouping-transparent multicol setup is needed.
%%
%% method:
%% providing macros \nobeginmulticols \noendmulticols that do essentially the same
%% but do not create a group.
%% I just removed the crucial \begingroup and \endgroup from \mult@@cols and \endmulticols.
%% Instead of relying on the TeX group restore mechanism, I have added macros
%% \save@mult@settings and \restore@mult@settings to mimick the grouping as far
%% as the settings for the multicol package are concerned.
%%
%% This is file `multicol.sty',
%% generated with the docstrip utility.
%%
%% The original source files were:
%%
%% multicol.dtx (with options: `package,badness,check,marktrace,nobalance,colbreak')
%%
%% This is a generated file.

%% In addition to the terms of LPPL any distributed version
%% (unchanged or modified) of multicol has to keep the statement
%% about the moral obligation for using multicol. In case of major
%% changes where this would not be appropriate the author of the

%%
%%
%% Moral obligation for using multicol:
%% ------------------------------------
%%
%% Users of multicol who wish to include or use multicol or a modified
%% version in a proprietary and commercially market product are asked
%% under certain conditions (see below) for 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/her judgment of the value of
%% multicol for his/her product.
%%
%%
%% The conditions for this are as follows:
%%
%% The producer of a proprietary and commercially market product
%% that involves typesetting using multicol is asked to determine
%% the value of a license fee for using multicol if
%%
%% - the product is a document and the producer has decided to
%% include multicol to typeset (parts of) the document or has
%% directed the author of the document to include multicol (for
%% example, by providing a class file to be used by the author)
%%
%% - the product is a LaTeX class or package that includes multicol
%%
%%
%% There is no moral obligation in case
%%
%% - the product is a document but producer has not directed
%% the author to include multicol (in that case the moral obligation
%% lies with the author of the document)
%%
%% - the product does not involve typesetting, e.g., consists, for
%% example, of distributing multicol and its documentation.
%%
%% - the product is not proprietary, i.e., is made available as free
%% software itself (which doesn't prohibit its commercial marketing)
%%
%% - multicol is used for non-commercial purposes
%%
%%
%% Determinating a license fee might result in a license fee of zero
%% (i.e., no payment) in case a producer has determined that the use
%% of multicol has no enhancing effect on the product. This is a
%% plausible scenario, i.e., in the above two cases the producer is
%% only asked to evaluate the value of multicol for the product
%% not for the payment of a license fee per se (which might or might
%% not follow from this evaluation).
%%
%% The license fee, if any, can be payed either to the LaTeX3 fund
%% (see ltx3info.txt in the base LaTeX distribution) or to the author of
%% the program who can be contacted at
%%
