An image on the SourceForge description appears to demonstrate a feature similar to facades:

But there is no description of what it is. There is however at least one closed issue ( #70 ) mentioning camouflage.

This is a request to add at least one sentence to the sourceforge description page, conveying how to use that feature.

The pipe wrench description explains how to add covers to pipes.

The time and energy expended to reply to this issue with a sentence could have more profitably been spent on one descriptive sentence on the SourceForge description page and reached a larger audience.

thanks for your aggressive input, but I still would have had to reply to this issue regardless.
