Re: [Reuseware-devel] call external tool in composition program

[Steffen Z. <Ste...@tu...>]

Hi,

I'm not sure, but wouldn't it be better to develop a new plugin with 
only your new concepts instead of changing 
de.tudresden.reuseware.fracola? And couldn't you, there, define a new 
language using the grammar inheritance mechanisms of Reuseware?

Just guessing...
