tool: D8: ABC to Postscript translator.
Usage: abcm2ps [options] file [file_options] ..
where:
 file        input ABC file, or '-'
 options and file_options:
  .output file options:
     -E      produce EPSF output, one tune per file
     -O fff  set outfile name to fff
     -O =    make outfile name from infile/title
     -i      indicate where are the errors
  .output formatting:
     -s xx   set scale factor to xx
     -w xx   set staff width (cm/in/pt)
     -m xx   set left margin (cm/in/pt)
     -d xx   set staff separation (cm/in/pt)
     -a xx   set max shrinkage to xx (between 0 and 1)
     -F foo  read format file "foo.fmt"
     -D bar  look for format files in directory "bar"
  .output options:
     -l      landscape mode
     -I xx   indent 1st line (cm/in/pt)
     -x      add xref numbers in titles
     -M      don't output the lyrics
     -n      include notes and history in output
     -N n    set page numbering mode to n=
             0=off 1=left 2=right 3=even left,odd right 4=even right,odd left
     -1      write one tune per page
     -G      no slur in grace notes
     -j n[b] number the measures every n bars (or on the left if n=0)
             if 'b', display in a box
     -k n[b] same as '-j' (abc2ps compatibility)
     -b n    set the first measure number to n
     -f      have flat beams
     -T n[v]   output the tablature 'n' for voice 'v' / all voices
  .line breaks:
     -c      auto line break
     -B n    break every n bars
  .input file selection/options:
     -e pattern
             xref list of tunes to select
     -u      abc2ps behaviour
     -L n    set char encoding to Latin number n
  .help/configuration:
     -V      show program version
     -h      show this command summary
     -H      show the format parameters
