[rbldnsd] "base template" documentation

[Oli Schacher]

Hi list

I'm playing with rbldnsd and having troubles understanding a
part of the man page section "Resulting A values and TXT templates": 

[snip]
       If the "base template" ($= variable) is defined, this template
is used for expansion, instead of the one specified for an entry being
queried.  Inside the base tem‐ plate, $= construct is substituted with
the text given for individual entries. In order to stop usage of base
template $= for a  single  record,  start  it  with  = (which will be
omitted from the resulting TXT value).  For example,

         $0 See http://www.example.com/bl?$= ($) for details
         127.0.0.2    r123
         127.0.0.3
         127.0.0.4    =See other blocklists for details about $

       produces the following TXT records:

         See http://www.example.com/bl?r123 (127.0.0.2) for details
         See http://www.example.com/bl?127.0.0.3 (127.0.0.3) for details
         See other blocklists for details about 127.0.0.4

[/snip]


With the example above, I didn't manage to get the results as
described. A TXT query for 127.0.0.2 returns just 'r123'. Shouldn't
that base template line start with $= instead of $0, or what is $0 in
this context exactly?

Why does the 127.0.0.3 example return the IP twice? From the
description I would have assumed that this returns "See
http://www.example.com/bl? (127.0.0.3) for details"

Is there a implicit "if there is no individual TXT, $= will be replaced
with the IP"  ? Further up it says "There is no default TXT value, so
rbldnsd will not return anything for TXT queries it TXT isn't
specified." (the "it" should probably be "if"), so I thought $= would
just be replaced with the empty string if I don't set any TXT value.
I'm probably missing something, but what? :-)

Thanks
Oli
