Setting width for one-measure example

[Albert Frantz]

Hello,

I'm trying to create an extremely simple one-measure example, but the measure is
extended across the page.  Can someone please help me to limit the length to
something reasonable?

I've searched through the archives and have tried the suggestions for setting
paper size and line / measure width, but Lily returns errors.  Obviously I don't
yet understand the structure of Lily files, so I please request that solutions
be entered directly into the file so that they work -- please don't just write,
"You need command xxxx" since I won't know what to do with it!

Many thanks in advance for your help.  The file is below.


Kind regards,

Albert
