DESCRIPTION

       mytool  is a my map file manipulation program in the yudit distribution.  It can generates
       so-called binary nbit ( my ) map file that  can  map  any  sequences  of  bytes  into  any
       sequences  of  bytes.  These sequences of bytes can be grouped into 1,2,4 and 8 bytes long
       words.  The input sequence length may be different from the matched sequence length. 'i  /
       'n  ->  'b  specifies that the word 'in' produces 'b' but only the 'i is consumed from the
       input buffer.

       It can also generate a so-called binary umap file, that maps 8 or 16 bit single words into
       16 bit single words and it contains the reverse map too.

       It can also disassemble the input map and produce a mys source file.

       The  input can be a binary umap file, a my file, mys file a uni and a kmap file for yudit.
       It is recommended that all kmap files use the new mys format because it gives more freedom
       to define the mapping.

       The  yudit  distribution has a simple document yudit/doc/my.doc on the binary map formats,
       and a source file example file yudit/mytool/my/example.mys please refer to this  for  more
       details.

OPTIONS

       -info  prints out a small information on the current map.

       -test  lets you test the map interactively.

       -showkeys
              show all the keys in the map file.

       -encode
              builds a state machine in the encoding part of the map file. The resulting map file
              can be written to disk with the -write option The resulting my  files  can  contain
              state  machines  to speed-up conversion. A state machine based my file can manifest
              10%-70% performance improvement, so it may be desirable for encoding fontmaps.  For
              fontmaps the bumap format might be better suited where only one character and not a
              sequence of characters need to be mapped.

       -decode
              builds a state machine in the decoding part of the map file.

       -strip strips off the state machines from the map files.  The -write option can be used to
              save the new map file.

       -benchmark
              option  performs  a  simple  benchmark  test  on  the map file, to compare speed of
              simple, state machine based and binary map based map files.

       -nocomment
              option strips all comments from an input source file of format mys  kmap  uni.   It
              does not strip comments from a binary file.

       -name new-name
              assigns a name to the map file.

       -comment new-comment
              assigns a comment to the map file.

       -type new-type
              assigns  a  map file a distinctive type, that can be kmap or fontmap but it is only
              informative. Keymaps can be used as fontmaps and vice versa.

       -write output-file
              writes the data into an output file.  mytool never modifies the original file.  All
              modifications  should  be explicitly saved with the this option.  Never specify the
              same file for input and output.

       -my input-file
              load a binary map file. Only one of this option can be specified.

       -mys input-source-file
              load a source file.

       -rmys input-source-file
              load a source file and reverse it - make encoding  from  decoding and vice versa.

       -kmap input-source-file
              load a source file in kmap format.

       -rkmap input-source-file
              load a source file and reverse it - make encoding  from  decoding and vice versa.

       -uni:l,u input-source-file
              load a source file in Unicode Consortium format. This format has the local code  in
              column l, and unicode in column u. The numbering of columns start from 0.

       -runi:l,u input-source-file
              load a source file in Unicode Consortium format and reverses it. Make encoding from
              decoding and vice versa.

       -8     option can be used with the -uni or -runi options. It specifies that the input is 8
              bit and not 16 bit.

       -high  option can be used with the -uni or -runi options. It specifies that the key should
              be or'ed with 0x8080.

       -low   option can be used with the -uni or -runi options. It specifies that the key should
              be and'ed with 0x7f7f.

       -convert output-file-format
              converts  the  map  file  to  a format. It is useful only when combined with -write
              option.  The possible formats are my -binary, mys -source, myc  -my-c-source,  umap
              -umap-c-source,  bumap  -binary-umap formats.  For maps where only a single 8 or 16
              bit local code  should be converted into 16 bit unicode and vice  versa,  the  umap
              file  formats  are  recommended.   The  c-source files are provided so that you can
              inlucde a full map into the c program.

DIAGNOSTICS

        mytool prints out an error message and exits with a non-zero status on error.   If  there
       is no error the exit status is zero.
