dc is the Desk Calculator for *nix; It works on reverse polish
notation, and a few other commands. The output of this routine
is a little jagged, as dc has no commands to control screen formatting.
Usage: dc 99bottles
where this source file is saved as 99bottles
NB: A blank line is required at the end of the file
Without it, dc will not quit.

sub-optimal output; I prefer my version (of course):
[[s]n]ss[[ bottle]n1ln!=s[ of beer]n]sb[ on the wall]sw[, ]sc[.]sp[2Q]sq[lnnlbx
lwnlcnlnnlbxlpp[Take one down, pass it around; ]nln1-sn0ln=qlnnlbxlwnlpplxx]sx
99snlxx[no more]nlbxlwnlpp
Or, somewhat less obfuscated:
[[s]n]ss
[[ bottle]n 1ln!=s [ of beer]n]sb
[ on the wall]sw
[, ]sc
[.]sp
[2Q]sq
[lnn lbx lwn lcn lnn lbx lpp
[Take one down, pass it around; ]n
ln1-sn 0ln=q lnn lbx lwn lpp lxx]sx
99sn lxx
