General Support: Help with htaccess - the final step to Textpattern integration

Thanks to the excellent changes to the Plogger gallery code in svn, I'm within a gnats whisker of getting it to work with my Textpattern installation.. I?ll be putting more details of my experience once I have complete success, but I?m left with one final problem that I lack the knowledge of how to change? the rewrite rules in the .htaccess file!

I think it highly likely that the changes necessary should be fairly easy, but after some playing it?s become clear that I just can?t wrap my head around the syntax. Here are the cruft-free rewrite rules inserted into the .htaccess file by each program:

#BEGIN Textpattern
<IfModule mod_rewrite.c>
RewriteEngine On
#RewriteBase /relative/web/path/
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^(.+) - [PT,L]
RewriteCond %{REQUEST_URI} !=/favicon.ico
RewriteRule ^(.*) index.php
RewriteCond %{HTTP:Authorization} !^$
RewriteRule .* - [E=REMOTE_USER:%{HTTP:Authorization}]
</IfModule>
#END Textpattern

# BEGIN Plogger
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteBase /plogger
RewriteCond %{REQUEST_URI} !(\.|/$)
RewriteRule ^.*$ http://mydomain.com%{REQUEST_URI}/ [R=301,L]
RewriteCond %{REQUEST_FILENAME} -d [OR]
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^.*$ - [S=2]
RewriteRule feed/$ plog-rss.php?path=%{REQUEST_URI} [L]
RewriteRule ^.*$ index.php?path=%{REQUEST_URI} [L]
</IfModule>
# END Plogger

The Plogger rewrite code changes this /ploggerpath/?level=album&id=1 into this /ploggerpath/collection1/gallery1/

The Textpattern rewrite code changes this /?s=section into this /section

If both programs are installed in the same base directory and the gallery is found in Textpattern section ?gallery?, the unaltered url would be

/?s=gallery&level=album&id=1

How would I need to change the rewrite rule to get it to something more useful, such as

/gallery/collection1/gallery1
