transpose

[Robert Jamison]

I have a number of pieces written in fakebook style that I want to 
transpose to other keys.
I know the command
\transpose c g should move things up a 5th (or maybe down a 4th).

I read the manual page on transpose, but I cannot figure out from that 
where to insist the command.
Everything I've tried has ended in numerous errors.
The models in the manual just don't show me how to do it.
And how do you transpose the chords?

For concreteness, the whole file is below.
I want it in C Major, instead of G Major -- up a fifth.
I'm sure if I see
how to do it once, I can do it ad infinitum.

Thanks,

Robert
