NAME

       hfst-subtract - =Subtract (minus) two transducers

SYNOPSIS

       hfst-subtract [OPTIONS...] [INFILE1 [INFILE2]]

DESCRIPTION

       Subtract (minus) two transducers

   Common options:
       -h, --help
              Print help message

       -V, --version
              Print version info

       -v, --verbose
              Print verbosely while processing

       -q, --quiet
              Only print fatal erros and requested output

       -s, --silent
              Alias of --quiet

   Input/Output options:
       -1, --input1=INFILE1
              Read first input transducer from INFILE1

       -2, --input2=INFILE2
              Read second input transducer from INFILE2

       -C, --do-not-convert
              Do not allow transducers to be converted into the same type

       -o, --output=OUTFILE
              Write results to OUTFILE

   Flag diacritics:
       -F, --harmonize-flags
              Harmonize flag diacritics

       -H, --do-not-harmonize Do not harmonize

       If  OUTFILE,  or  either  INFILE1  or  INFILE2  is missing or -, standard streams will be used.  INFILE1,
       INFILE2, or both, must be specified.  Format of result depends on format of  INFILE1  and  INFILE2;  both
       should have the same format.

       The  operation is applied pairwise for INFILE1 and INFILE2 that must have the same number of transducers.
       If INFILE2 has only one transducer, the operation is applied for each transducer in INFILE1  keeping  the
       second transducer constant.

EXAMPLES

       hfst-subtract -o catdog.hfst cat.hfst dog.hfst
              subtracts transducers
