Reading Apache config info from mod_perl

[starfire]

How can I get at the value of Apache config directive like AuthUserFile
or Port from within my mod_perl code?  I don't want to pass the
values using PerlSetVar because that would require the sysadmin to edit
both the Apache config directive and my PerlSetVar if he makes a change -
too error prone.
