Singularity handling in NIntegrate

Hi all,

I've been searching around for information about the particular
method(s) that NIntegrate uses to handle singularities at the endpoints
of a numerical integration. In particular,

1. How is the SingularityDepth option used? Is it just the number of
recursive bisections of the first/last subinterval of integration
before a singularity is assumed?

2. What is/are the coordinate transformation(s) used when a singularity
is detected?

Thanks for any help you can give me with these questions.

Cheers,

Andrew
