-Information on ProMod3 may be found at doc/html/index.html. 
+ProMod3 is a modelling engine based on the OpenStructure computational 
+structural biology framework (openstructure.org) 
+that can perform all steps required to generate a protein model by 
+homology. Its modular design aims at implementing flexible modelling 
+pipelines and fast prototyping of novel algorithms.

I assume you have a TODO list somewhere stating that something should follow after the ":"? ;-)

[Studer Gabriel]

Yes I do :)
