Well, I have a little perl script that I use a lot to transpose fragments (that may not include a K: line). It's convenient, but I do have to watch its accidentals. For example, if the source is K:Dm and the target is K:Em, a _B transposes to _c, which is usually not correct. In Dm, you might well see _B, for example to cancel an earlier =B. My code in fact would transpose the =B correctly to ^c, but it isn't smart enough to figure out when _c should be just c. I don't know of a way to do a correct transposition without knowing at least the key signature. Even if you know the tonic, you also need to know the mode to stand a chance at getting all the accidentals right. OTOH, it's very useful to be able to transpose fragments of music, so I have my little script. But I do have to proof-read its output.
