wip/songwrite2 0.4.1 NetBSD

Songwrite 2 is a music score and songbook editor. This software is especially designed for musicians who do not master solfege (like me!) and to Linuxian musicians. Songwrite 2 can edit staffs, but also tablatures (for guitar, bass, banjo, lyre, diatonic accordion,...) and flute fingerings (for tin whistle, recorder,...); it also manages lyrics. Songwrite 2 can play and print the partitions.
