Writing debian/watch for project located at ohloh

[Resul Cetin <Resul-Cetin@gmx.net>]

Hi,
I am currently trying to create a package for something which hosts its files 
only on ohloh's download services. The files can be found at
 https://www.ohloh.net/p/mereo/download?package=stable

I started with following file:
---
version=3
https://www.ohloh.net/p/mereo/download?package=stable \
/p/mereo/download\?filename=mereo_(.*)_src.zip
---

This works quite good to get informed about the current version, but the 
download doesn't work at all.

 $ uscan --download
 cppcheck: Newer version (1.8.0) available on remote site:
   https://www.ohloh.net/p/mereo/download?filename=mereo_1.8.0_src.zip
   (local version is 1.3)
 cppcheck: Successfully downloaded updated package download

Will (as you can read above) only create a file called 'download'. Inside is a 
html file with the link hidden somewhere. Does anyone has experience or an 
idea how to write a working debian/watch file for such a project?

Greetings,
Resul Cetin
