       g3cat - concatenate multiple g3 documents

       _g_3_c_a_t  concatenates  g3  files. These can either be 'raw',
       that is, bitmaps packed according to the CCITT  T.4  stan-
       dard  for  one-dimensional  bitmap  encoding, or 'digifax'
       files, created by GNU's GhostScript package with the ddiiggii--
       ffaaxx  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.

       --a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.

       --ll     separate files with a one-pixel wide black line.

       --hh <<bbllaannkk lliinneess>>
              specifies  the  number  of blank lines _g_3_c_a_t should
              prepend to each page. Default is 0.

       --ww <<wwiiddtthh>>
              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 transparently fixed.

       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
