This is the Debian port of the abcm2ps program by Jean-François Moine. The program translates tunes written in the ABC format to PostScript, which can then be viewed using Ghostview et al. or printed on a PostScript printer or through Ghostscript. It supports various semi-standard extensions to the ABC standard, such as multiple voices and staves.
This program is a vastly improved spin-off from Michael Methfessel's abc2ps, which continues to be available for the time being. In particular, it contains a lot of extensions to help typeset classical music.
