Adding performance notes (text) to score?

[Lance Hoffmeyer]

Hey all,

Is there a way to add performance notes in lilypond?  
I want to add two or three lines of text below the staff 
at a certain point or create footnotes at the bottom of the
page.

As an aside, how can I produce a jagged line along the staff?
This is typically used as a way to indicate a fingernail scraping
across a guitar string.  I put in a \glissando with a \markup 
indicating what I wanted but would prefer the jagged line if possible.
