NAME
pmxchords - This script processes pmx files with chord symbols, allowing for key transpositions
SYNOPSIS
[ texlua ] pmxchords { option | jobname [ .pmx ] } ... The default effect is to preprocess each pmx file so that chords are transposed as necessary, generating a temporary pmx file which is then processed by pmxab. Finally the resulting tex file is renamed to have the original jobname. The default filename for the temporary file is <jobname>_chtr.pmx.
OPTIONS
-v output program name and version number, and quit -h output usage summary and quit -s stop after first step (of producing a temporary pmx file with transposed chord symbols).
SEE ALSO
