|Briefly:||Auto transpose chords written as text.|
|Usage:||php transpose_chords.php <range> [<hint>] ["strict"] ["font="<fontname>]|
|Additional Help :||
eg php transpose_chords.php -4 C# font=StaffBold
If range is 0, and no hint is given, convert all enharmonic spellings
If range is not 0, and no hint is given, transpose according to "C"
A "text chord" is a piece of text of the regular-expression form
\s*[A-G][#b]? (leading space, uppercase A-G, optional # or b)
Trying to match the dim, dom, maj, aug, sus4, +9, add11, etc was considered fruitless but a keyword "strict" is available to try and limit what we call a chord
\s*[A-G][#b]? ?(M|maj|m|min|dim|dom|sus|aug|add|7|9|11|13|b5|b11|b13)?(as above, but with optional trailing space followed by optional chord modifiers).
