Here's some of the relevant documentation of the user.txt expressions Kyle
mentioned.  It is possible to set session variables and get them to be
logged - we're doing this with certain Shibboleth attributes for business
analysis.  I have not had luck getting variables other than session vars
set at the user's moment of login to be logged though.
