NAME
     g3cat - concatenate multiple g3 documents

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

DESCRIPTION
     g3cat  concatenates  g3  files. These can either be 'raw', that is, bitmaps
     packed according to the CCITT T.4 standard for one-dimensional  bitmap  en-
     coding,  or  'digifax' files, created by GNU's GhostScript package 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 stan-
	    dard 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 transparently 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
