Thanks! However, I haven't found any explanation of what those numbers mean. I need
the tempo in BPM.
I found this formula in the Rosegarden source:
qpm = (60.0 * beatTime) / (beatSec * quarter)
But of the three numbers that songtimeinfo spits out, I haven't been able to figure
out which one is beatTime, beatSec, and quarter.

Is there any command-line tool to extract and print the tempo of
a MIDI file?
hi,
you could use midish for that: import the .mid file, and use the
songtimeinfo function; example:
$ rmidish
send EOF character (control-D) to quit
1> songimportsmf "sample.mid"
2> songtimeinfo
{
timesig 4 24
tempo 400000
}
