This should enable us for keepeng the eln-cache folders clean and solve the issue mentioned in my previous message. So far I've no idea if hashing the source file content has a measurable impact on the startup time tho, I guess we'll see and in case search for a different solution. Andrea -- akrl@sdf.org
