Manual File Problem

[Richard S Dougall]

I want to generate a Postscript version of the Lilypond Manual.

I have download the file

        lilypond.ps.gz

which is suppose to be a gnu-zipped file.  When I try to
unzip this with gunzip on the Univ. of Pittsburgh's unix
system, it tells me that this file is not a gzip file or
some similar messages.  I have try several variation of
collecting the file and trying to unzip it, but have
not had any success.

Do you have any suggestions?  Could it be that the
zipped manual file is corrupted?

Any help you can supply would be welcomed.
