Hi,

This does not help you with converting Mapnik styles to SLD, but if you find
some WMS server that looks good and that supports the GetStyles request you can
capture the styles. For example this site doew answer for GetStyles:
http://mapbender.wheregroup.com/cgi-bin/mapserv?map=/data/umn/osm/osm_basic.map

This returs SLD for the layer "Bahn":
http://mapbender.wheregroup.com/cgi-bin/mapserv?map=/data/umn/osm/osm_basic.map&VERSION=1.1.1&REQUEST=GetStyles&SERVICE=WMS&layers=Bahn

You can use this SLD on your own server as it is or edit it if you like, or you
can even ask the wheregroup server to use your modified SLD for styling the Bahn
layer by adding a reference to your own style into your GetMap request with &SLD
parameter. I have not tried if wheregroup server supports using own SLD files
but if it does then something like this might work:

&SLD=http://your_server.org/my_styles/my_bahn_style.xml
