How to do a Barré in guitar music?

[Arjan Bos]

Dear list,

First of all, does anyone of you know the English word for the Dutch  
word Barré? I could not find it in the Music Glossary.
Second of all, does anyone of you how to draw it in lilypond? I've  
attached an example of what I'm looking for. I'm looking for a way to  
draw the vertical bracket that appears before the first note.

Regards,

A.J.
