+%%% TeXChord.  Macros for typesetting guitar-chord diagrams.
+%%% Version 0.8.

+%%%
+%%% This package defines macros for producing guitar-chord diagrams
+%%% with TeX.  In general, the command to produce a chord pattern
+%%% consists of three parts: the chord name, modifiers, and the
+%%% string ``chord.''  Upper-case letters are used for Major and
+%%% lower-case letter for minor.  Possible modifiers are ``s'' for
+%%% ``seven,'' ``sh'' for ``sharp,'' ``f'' for ``flat'' and ``S''
+%%% for ``major seven.'' When they are mixed, the incidentals
+%%% (sharp, flat) preceed the others.
+%%% 
+%%% So, for example, \Cchord is a simple C-major chord; \cshchord is
+%%% a c-sharp-minor chord; \DshSchord is a D-sharp-major-seven chord.
+%%% As of version 0.8, I have not entered all of the possible chord
+%%% patterns.  See the end of this file for examples of how to add
+%%% chords of your own.
+%%%
+%%% I have included the chord patterns I usually use; your
+%%% choices for some obscure chords may vary.  Again, you can add
+%%% your own chords by copying the examples at the end of this file.
+%%% 
+%%% I have included both sharps and flats for every chord, even
+%%% though some are seldom used (C-flat comes to mind).  As of
+%%% version 0.8, many chords are still missing.  Sorry.
+%%%
+%%% In addition to the chord macros themselves, the following
+%%% ``control'' commands are provided:
+%%% 
+%%% \bigchords		Use big chord patterns.
+%%% \smallchords	Use small chord patterns.
+%%% \raisedchords	Place chords over text at current location.
+%%% \textchords		Place chords in current text.
+%%% 
+%%% For example, if you wanted to discuss chords, you might say:
+%%% 
+%%% \smallchords\textchords This is how a C-chord is played:  \Cchord.
+%%% 
+%%% On the other hand, in music, you might use:
+%%% 
+%%% \bigchords\raisedchords \Dchord This is played with a D-chord.
+%%%
+%%% \bigchords\raisedchords is the default.
+%%%
+%%% I don't know how reliable the \raisedchords is.  You may have
+%%% to tweek the definition of \raisedchords at the end of this
+%%% file if you are not using 10pt text.
+%%%
+%%% Other dimentions you can freely change are \chordheight and
+%%% \chordwidth.  Be sure to do so both in the initialization and
+%%% in the definitions of \bigchords and \smallchords.  Also
+%%% change \extchordheight to match \chordheight.  Feel free to
+%%% change the fonts, too.
+%%%
+%%%
+%%% --> I would like to thank Merri Lovinger Arian, a long time friend
+%%% --> and my guitar teacher, without whom I would never have learned
+%%% --> the joy of guitar. 
+%%%
+%%%
+%%%
+%%% By version 1.0, this package will also have better provisions
+%%% for bar-chords; provisions for optionally printing the name of
+%%% the chord to the left of (instead of above) the diagram;
+%%% provisions for printing fret-numbers to the left of the
+%%% diagrams, instead of the hideously ugly extended patterns;
+%%% provisions for printing little x's and o's atop the chord
+%%% patterns to indicate which strings are sounded.  Also, the
+%%% code will be cleaned up and commented.  
+%%%
+%%% Other bugs include numerous spacing problems, most notably in
+%%% f-minor chords.
