%%            Report bugs to T.J. Allen (tjallen@wishep.physics.wisc.edu
%%            or  tja@theory3.caltech.edu)
%%
%%            This will NOT produce double columns in preprintmode since
%%            there are conflicting \output commands.  The whole
%%            macro should be rewritten using a modified \output.
%%
%%            Where you want
%%            the doublecolumn output to start, use \begindoublecolumns.
%%            Where you want to go back to single columns use
%%            \enddoublecolumns.  This produces output much like that
%%            of RevTeX.  If you wish to specify that there be a rule
%%            between the columns of output, then set \columnrulewidth
%%            = 0.4pt.

%%       Here is the draftmode feature
%%
%%       Use the following on the preliminary draft,
%%       puts time/date on each page in writes labels in margins
%%       and puts reference labels on the reference page.
%%       Putting \draft in the beginning of the paper causes it
%%       to be printed in draftmode.  use \nodraftlabels to get rid of
%%       eqn, ref, and fig labels in draft mode
%%
%%       Timestamp routine bug fixed October 30, 1991 by T.J.A.

%%    Macro to make mailing labels on Avery sheets from an address file.
%%    Address file should be formatted as:
%% 
%%       {
%%       <name>
%%       <multi(<=5)line address>
%%       }
%%
%%       with a blank line between addresses and NO BLANK LINES at the 
%%       BEGINNING or the END
%%
%%       The enhanced phyzzx.plus automatically formats the input file for 
%%       addresses correctly if the command \labelformlabels is inserted 
%%       BEFORE the \multiletter command 
%%   
%%  The present format has ELEVEN labels in each column, THREE columns/page
%%  and prints in a tenpoint san serif typeface
%%  (Appended to the end of this file is the format for EIGHT labels/column)
%%
%%   No matter what the name of the address file input is, the output will
%%   be called LABELFORM.DVI
