How to find installed location of supporting files   

Hi,

My DSL has some supporting files, which need to be accessed at run-time. The 
installed package is running from GAC, so the location of the executing 
assembly does not point to these files.
What would be the preferred way to find the installed location?

Many thanks in advance,
Steffen
