would have had a really hard time implementing the 'edge splitting' on<br>
my own. So I'm really grateful I found the wrappers. On the other hand<br>
the wrapper I used wasn't even included in pgrouting, so I guess we'd be<br>
safe to have them outside the distribution, either in the docs or as an<br>
external download.<o:p></o:p></span></font></p>

a lot of stuff, that we don't know if it work with the current release. I think
we would be more inclined to have a wiki page that links to 3rd party github
projects or have a tips and tricks wiki page. The ideal situation is that we
link to a page the you maintain because that de-clutters the pgrouting maintained
pages and files.<o:p></o:p></span></font></p>
