1.  Introduction
       "MusicXML", ( http://www.musicxml.com/ ) originally developed by Recordare INC
       and now owned by Finale ( https://www.finalemusic.com/ ), is the leading
       music data exchange format. XML2PMX provides an import facility for
       sheet music stored in MusicXML format to PMX and MusiXTeX, the leading free
       software for musical typesetting. Thus PMX is able to import published
       MusicXML sources as well as MusicXML sources created by OCR scanning,
       e.g. with Sharpeye of VISIV ( http://www.visiv.co.uk )or PhotoScore.

2. PMX
       developed by Don Simons (dsimons(at)roadrunner(dot)com) is an easy to use,
   yet powerful preprocessor for the musical typesetting system MusiXTeX.
       http://icking-music-archive.org/software/htdocs/index.html
       An excellent introduction to using PMX is
               http://icking-music-archive.org/software/pmx/pmxccn.pdf
       In order to work successfully with XML2PMX a good knowledge of
       PMX is required, and of MusiXTeX will be helpful.

3. XML2PMX
       has been developed by the author with "Oberon Plugin for Windows
       Version 2.5" of ETHZ Zürich on Windows 10.
       https://github.com/Spirit-of-Oberon/ETH-Oberon-PlugIn-Win32
       and OLR (Oberon Linux Revival)
       http://oberon.wikidot.com/oberon-linux-revival-olr

   XML2PMX is available as Windows-EXE (32 Bit) and as Linux binary (32 Bit).
       XML2PMX requires a TeX, MusiXTeX and PMX installation.
       For Unix please see:   https://tug.org/texlive/
       For Windows please see: https://miktex.org/2.9/setup

4. Coverage of MusicXML features
       The following MusicXML features are detected and translated to PMX:
               - 24 staves/voices and 600 bars
               - 83 notes per instrument and bar
       - two voices per staff
       - maximum of two staves per instrument
       - notes and rests up to 64th, including tuplets and grace notes,
       - maximum of 2 dots
       - chords, accidentals
       - some annotations like Fermata, Staccato, Tremolo etc.
       - ties, slurs and beams
       - definition of meter, fifths, clefs and their changes on the fly
       - dynamic marks: hairpins, "ff" etc., piano damping pedal
       - title and composer, and texts above or below the staff
       - barlines, repeats, volta
       - instrument names,
       - Accepts Windows files  (records ended by 0DX OAX)
                 as well as Unix files  (records ended by 0AX).
               - Resulting PMX-file on Unix has records ended by 0AX.
               - Resulting PMX-file on Windows has records ended by 0DX 0AX.
               - will not accept UTF16

5. Additional features:
       - command line input fields: "options" and "maxbar".
         "options" may contain one or several of the nine letters "pdvalstgr"
         in arbitrary sequence in upper or lower case and without spaces.
         Option "r" removes any note which has been marked in XML with
         print-object = "no".
         "maxbar" is a limit on the number of bars to be processed.
         When maxbar = 0 then all bars will be processed.
       - With option = "L" Lyrics can be extracted and stored in a separate file: "songtext.txt".
       - Automatic detection of pickup

6. Limitations
       Some more elaborate situations like beams crossing staves or chords crossing staves
       have not yet been covered.
       MusicXML attributes are enclosed with double quotes.

7. Usage on MS Windows command line (quotes not required):
   ============================================================================
       XML2PMX_2020.exe
       "xml-file with path" "pmx-result-file with path" "output options" "maxbar"
       ============================================================================
       There are two obligatory inputs: "xml-file" and "pmx-result-file".
       "output options" and "maxbar" are optional parameters.
       "output options" contains a sequence (without blanks) of one or several of
       the letters  "p", "d", "v", "a", "l", "r", "s", "t" and "g" .
       Their meaning is the following:
        _____ _______________________________________________________
       |  p  | XML parser: can produce much output                   |
       |-------------------------------------------------------------|
       |  d  | information on "directions" (dynamical marks etc)     |
       |-------------------------------------------------------------|
       |  v  | distribution of voices over instruments and measures  |
       |-------------------------------------------------------------|
       |  a  | statistics of MusicXML tags like <note>, <measure>,   |
       |-------------------------------------------------------------|
       |  l  | extracts lyrics in a separate file                    |
       |-------------------------------------------------------------|
       |  s  | removes all slurs                                     |
       |-------------------------------------------------------------|
       |  t  | removes all ties                                      |
       |-------------------------------------------------------------|
       |  g  | uses PMX slur option inside grace note                |                 |
       |-------------------------------------------------------------|
       |  r  | remove Notes with Print-object = "no"                 |
   ---------------------------------------------------------------
       The generated PMX file will in general be complete and can be
       processed by PMX.If not, you can often solve the problem with
       minor changes in the PMX code.

       Depending on the options chosen, you will find intermediate results in the
       console window which may be helpful for debugging.
