        Ugh... it's a problem to get that output. Remember I wrote about
being unable to get stdout output in 2.5.x? Well, this problem persists 
in 2.6.0.  Anyway if I do tail -f moon.log (source moon.ly) in other window 
every string appears after delay. One string, delay... another string, 
delay... etc. But I think moon.log output is buffered, so it's no help 
in debugging. 
        BTW, it takes several seconds before moon.log is created, about half 
of the whole run. I erased moon.log and compiled it again and it took
18 seconds total and during first 8 seconds moon.log wasn't even created.
The file is simple, one-page (and the problem exists when I compile any 
file, simple or complicated).

$ time lily.sh --verbose --pdf --png moon.ly

real    0m18.177s
user    0m0.050s
sys     0m0.060s

After about 7-8 seconds of waiting during the run I get this output in 
another window:

$ tail -f moon.log

        If I run 2.6.0 with nonexistant file as input file, it takes 8 seconds
before it opens lilypad window with "warning: can't find file: `nonexistant.ly'"

$ time lily.sh --verbose --pdf --png nonexistant.ly

real    0m8.153s

sys     0m0.070s

(I just closed lilypad window as soon as it came up).

        PDF and PNG conversions (two dos windows) run very quickly at the end.
