       autosp  -  preprocessor  to generate note-spacing commands for MusiXTeX

       This  program  makes  it easier to create MusiXTeX scores by converting
       (non-standard) commands of the form \anotes ... \en into  one  or  more
       conventional  note-spacing  commands (\notes \Notes \NOtes ...), deter-
       mined by the actual note values, with \sk spacing commands inserted  as
       necessary.  The coding for an entire measure can be entered one part at
       a time, without concern for note-spacing changes  within  the  part  or
       spacing requirements of other parts.

       For example, if applied to

           \anotes\qa J\qa K&\ca l\qa m\ca n\en

       autosp generates

           \Notes\qa J\sk\qa K\sk&\ca l\qa m\sk\ca n\en

       Typically,  an  \anotes  command  is expanded into several conventional
       note-spacing commands.

       If the infile argument has .tex extension, autosp will process  conven-
       tional  note-spacing  commands  (but not \vnotes or \znotes) similarly.
       This is intended to correct spacing in an  extracted  single-instrument
       part, but may not produce satisfactory output when applied to a conven-
       tional multi-instrument MusiXTeX score.

       If the infile argument has neither .aspc nor .tex extension,  input  is
       taken  from  infile.aspc if that file exists, or from infile.tex other-

       For \anotes commands (and, for a .tex file, all conventional note-spac-
       ing commands), line breaks and spaces may precede note segments, allow-
       ing more flexible source formatting; the line breaks and spaces will be
       elided from the output.

       For example,


       is acceptable and generates


       If  no  outfile  argument is provided, output goes to infile.tex if the
       infile name has extension .aspc, or to standard output otherwise.

       If the -l ( --log ) option is used, a log infile.alog is generated.

       If the -d ( --dotted ) option is used, dotted beam notes  of  the  form
       \qb{n}{.p} are not given extra space; it is assumed that the subsequent
       note will be shifted by a \roff-like command or a spacing command  such
       as  \qsk  or  \hqsk.   Commands  of  the  form  \qlp{p}, \qlpp{p}, ...,
       \qpb{n}{p} and \qppb{n}{p} are always spaced as indicated.

       If there is a single staff, consecutive whole-bar rest bars are  merged
       into  a multi-bar rest. Bar-centered rests can be coded using the stan-
       dard \def\atnextbar notation but also the non-standard command  \Cpause
       in a note segment generates a bar-centered rest.

       Spacing  commands  \sk  and  \hsk  in the source are discarded, but not
       \qsk, \hqsk or \qqsk; moreover non-standard commands  \Qsk,  \HQsk  and
       \QQsk generate "global" skips; i.e., the effect of \qsk, \hqsk or \qqsk
       in every staff.

       A note segment can be completely empty, but if a  note  segment  should
       start  with  or contain a "space," the note-value of that space must be
       made explicit with a command  of  the  form  \ha{*},  \qa{.*},  \qa{*},
       \ca{*}, etc.

       All other conventional MusiXTeX commands are output exactly as given in
       the input.

       autosp determines the spacing for ordinary notes from the note commands
       themselves; for example,

       +  \qa, \qu, \ql, \qp result in \NOtes;

       +  \ca, \cu, \cl, \ds result in \Notes;

       and so on.

       The spacing for beamed notes is determined by the beam multiplicity, so
       that \ib... results in \Notes, \ibb... results in \notes, etc.

       Collective coding of note sequences (including accidentals and dots) is
       handled  by  expanding  the sequence into a sequence of individual note

       autosp  assumes  that  &  and  |  (rather  than   \nextinstrument   and
       \nextstaff) are used to separate instruments and staffs.

       Appoggiaturas  and  grace notes are recognized by the use of \tinynote-
       size; note-spacing of 1.45\elemskip is used. If this isn't suitable and
       can't  be  corrected  with  a  small  skip,  a \vnotes command with any
       desired spacing can be used.

       autosp supports x-tuplets introduced  using  \xtuplet{x}  and  triplets
       introduced  using  any of the following commands (regardless of any re-
       definition of \txt or \tuplettxt):


       However, MusiXTeX notation does not specify the intended duration of an
       x-tuplet.   autosp  assumes that an x-tuplet is to be played in (x-1)/x
       of the apparent x-tuplet duration.   So,  for  example,  a  triplet  in
       eighths  is  assumed  to be played in the time of one quarter note.  If
       this assumption isn't valid, the  x-tuplet  must  be  coded  explicitly
       using  a \vnotes command; see the first measure of barsant2.aspc for an
       example of a non-standard x-tuplet: a 5-tuple of  64th  notes  with  an
       intended  duration  of six 64ths.  autosp cannot deal with simultaneous
       x-tuplets in multiple staffs unless the x values and note durations are
       identical.  Global  skips  (\QQsk, \HQsk and \Qsk) are ineffective if a
       staff has an x-tuplet; however, "local" skips (\qqsk, \hqsk, \qsk)  are

       User-defined macros are not processed or expanded.

       All  staffs are assumed to have the same meter; see kinder2.aspc for an
       example of how to work around this.

       autosp may not be effective for music with more than  one  voice  in  a
       single  staff.  It  might be advisable to use a separate staff for each
       voice, to avoid \anotes when necessary, or to omit certain voices  ini-
       tially and add them into the resulting TeX file.

       See  files  quod2.aspc,  kinder2.aspc, geminiani.aspc and barsant2.aspc
       for scores suitable for input to autosp.
