Hi Nicola,

    [...]
    mpost -recorder -output-directory ./mydir ./mydir/foo.mp

    the file foo.fls is written into the current directory and not into 
    ./mydir. I consider this as a bug.  [...]

I do too.  And independent of mpost, the same behavior was in the other
binaries (tex, mf, etc.).  I have checked in a patch which fixes it, to
my tests anyway.

Thanks,
Karl
