%%%
%%% 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.
