Lilypond & Ubuntu

[Peter Gifford]

I am struggling to get Lilypond even running in the latest Ubuntu.  It seems to
have downloaded and extracted in a Lilypond folder but I cannot find a way to
run it - even in terminal by typing Lilypond.

Any help you can give me would be very much appreciated.  I have used this some
months ago on a colleagues pc and it looked superb, exactly what I need for
scoring music written for our church.

Thanks in anticipation......  Peter Gifford, Radlett, UK
