NAME
       g3cat - concatenate multiple g3 documents

SYNOPSIS
       g3cat [-l] [-a] g3-file1	...

DESCRIPTION
       g3cat  concatenates  g3 files. These can	either be 'raw', that is, bit-
       maps packed according to	the CCITT  T.4	standard  for  one-dimensional
       bitmap encoding,	or 'digifax' files, created by GNU's GhostScript pack-
       age with	the digifax drivers. Its output	is a concatenation of all  the
       input files, in raw G3 format, with two white lines in between.

       If a - is given as input	file, stdin is used.

       If the input data is malformed, a warning is printed to stderr, and the
       output file will	have a blank line at this place.

OPTIONS
       -l     separate files with a one-pixel wide black line.

       -h <blank lines>
	      specifies	the number of blank lines g3cat	should prepend to each
	      page. Default is 0.

       -L <lines>
	      limit lenght of output page to maximum <lines> lines.

SPECIAL-CASE OPTIONS
       -w <width>
	      specifies	 the desired page width	in pixels per line. Default is
	      1728 PELs, and this is mandatory if you want to send the fax  to
	      a	standard fax machine.  If one of the input files doesn't match
	      this line	width (for example because it was created by a	broken
	      G3  creator), a warning is printed, and the line width is	trans-
	      parently fixed.

       -a     byte-align the end-of-line codes (EOL) in	the  file.  Every  EOL
	      will end at a byte boundary, that	is, with a  01 byte.

       -p <pad>
	      specifies	 a  minimum number of bytes that each output line must
	      be padded	to.  Padding is	done with 0-bits before	the EOL	code.

       -R     suppress output of end-of-page code (RTC).

Example
       The following example will put a	 header	 line  on  a  given  g3	 page,
       'page1' and put the result into 'page2':

       echo '$header' |	pbmtext	| pbm2g3 | g3cat - page1 >page2
