Mutopia .ly files don't "compile" ?

[Blunt Jackson]

Hi,

I'm just trying to get the hand of lilypond, & I thought I would grab
some .ly files from mutopia
to use as lessons. Unfortunately, of the first batch I downloaded, not
one "compiles" under
lilypond. They all report zillions of errors: unknown tags, unmatched
braces, syntax errors
of numerous sorts.

Are the mutopia .ly files *really* all messed up, or do I need to do
something special to
process them? I can post logs & whatnot; but I thought maybe it's just
something obvious
and dumb that I am missing...
