DVIDVI(L)							     DVIDVI(L)

NAME
       dvidvi -	selects	and/or re-arranges pages in a TeX dvi file

SYNOPSIS
       dvidvi [param] infile outfile

DESCRIPTION
   Introduction
       The dvidvi program converts a dvi file into another dvi file, with per-
       haps certain changes.

   Parameters
       -f n	 page n	is first page selected
       -l n	 page n	is last	page selected
       -n n	 select	at most	n pages. Notice	that n is the number of	 pages
		 selected,  independently of the number	of pages actually con-
		 tained	in a sheet
       -i { n1..n2 | n1	}[,...]
		 include pages (ranges allowed). When  this  option  is	 used,
		 ONLY  the  specified  pages are selected. However, we can ex-
		 clude from these pages	with the option	-x
       -x { n1..n2 | n1	}[,...]
		 exclude pages (ranges allowed)
       -q	 work in quiet mode, that is do	not print in the  screen  mes-
		 sages of how the work is being	done.
       -r	 reverse the order of the pages.

       The page	numbers	for the	above options -f -l -i and -x can be specified
       in different ways.
       1)  If a	number n is given, it is interpreted as	the n'th page from the
	   beginning  of  the .dvi file. Of course, this number	is independent
	   of the page number assigned by TeX.
       2)  TeX page numbers are	those who are actually written	in  the	 page;
	   these  page	numbers	can be modified, for example, by using the TeX
	   commands   \pagenumbering,	\setcounter{page}{n},	and    \addto-
	   counter{page}{n}.   A TeX page number can be	specified by preceding
	   the number n	with the character @. Thus, if you specify -f  @25  -l
	   @30	you  select  the  pages	between	25 and 30, these numbers being
	   those assigned by TeX.
       3)  However, several pages can have the same TeX	page number in a  .dvi
	   file.   For	example, the introductory pages	in a book are numbered
	   i, ii, and so on until the first chapter begins and then, the pages
	   are	numbered  1, 2,	etc.  In this case, the	pages numbered i and 1
	   in the .dvi file have the same TeX page number. If you want to  se-
	   lect	 for example the second	occurrence of the page numbered	1, you
	   can specify a page number as	(@2)1. Thus @1 is equivalent to	(@1)1.
	   For	example, if you	specify	-f (@2)1 -l(@2)10 you select the pages
	   between 1 and 10 of the first chapter, not the  introductory	 pages
	   between i and x.

       There  is  another  parameter  that tells dvidvi	how you	want to	change
       page layout and specifications.	This is	the -m parameter.
       *   The number preceding	the colon is  the  modulo  value.   Everything
	   will	 be  done  in chunks of	pages this big.	 If there is no	colon,
	   than	the default value is assumed to	be one.	  The  last  chunk  of
	   pages is padded with	as many	blank pages as necessary.
       *    Following  the  colon  is  a comma-separated list of page numbers.
	   These page numbers are with respect to the current chunk of	pages,
	   and	must lie in the	range zero to the modulo value less one.  If a
	   negative sign precedes the number, then the page is taken from  the
	   mirror chunk; if there are m	chunks,	then the mirror	chunk of chunk
	   n is	the chunk numbered m-n-1.  Put simply, it is  the  chunk  num-
	   bered  the  same,  only  from the end.  This	can be used to reverse
	   pages.  If no number	is given, the page number defaults to 1.
       *   Following each page number is an optional offset value in parenthe-
	   sis,	 which consists	of a pair of comma-separated dimensions.  Each
	   dimension is	a decimal number with an  optional  unit  of  measure.
	   The	default	unit of	measure	is inches, or the last unit of measure
	   used.  All units are	in true	dimensions.  Allowable units  of  mea-
	   sure	are the	same that TeX allows: in, mm, cm, pt, pc, dd, and cc.

EXAMPLES
       -m  -	  Reverses the order of	the pages.  This time, both the	modulo
		 and the page number are defaulted.
       -m 2:0	 Selects the first, third, fifth, etc. pages  from  the	 file.
		 Print	this one after printing	the next, taking the paper out
		 of the	feed tray and reinserting it into the paper feed.
       -m 2:-1	 Selects the second, fourth, etc. pages, and  writes  them  in
		 reverse order.
       -m 4:-1,2(4.25in,0in)
       -m 4:-3,0(4.25in,0in)
		 Useful	 for printing a	little booklet,	four pages to a	sheet,
		 double-sided, for stapling in the middle.   Print  the	 first
		 one,  put  the	 stack	back into the printer upside down, and
		 print the second.  The	`in' specifications are	superfluous.
       -m ,(1pt,1)
		 Scare your system administrator!   Actually,  things  are  so
		 blurry	with this option, you may want to send enemies letters
		 printed like this.  *Long* letters.
       -m 4:0(5.5in,4.25),3(0,4.25)
       -m 4:1(0in,4.25),2(5.5,4.25)
		 Print a four-page card	on one sheet.  Print the first,	rotate
		 the  paper 180	degrees	and feed it again.  (PostScript	people
		 can do	funny tricks with PostScript so	this isn't necessary.)
