     print "$_\n" ;
 }

DESCRIPTION

ABC music archives (http://www.gre.ac.uk/~walshaw/abc/index.html) contain songs in the ABC format. They are a very quick way for entering music in a text format, and there are numerous publishable quality renderers for ABC music. This module encapsulates the ABC archive, and individual songs so they may more easily be managed by perl front-ends.

ABSTRACT

    ABC music archives (http://www.gre.ac.uk/~walshaw/abc/index.html) contain songs in the ABC format.
