Hi,

I have a library with optional multi-channel support. If you try to create the object with the "-m" flag and Pd does not have multi-channel support, it would print an error message. This works all fine, but there's a tricky problem with the help patches. Of course, I want to document the multi-channel feature, but I don't want the help patch to print errors when loaded in older Pd versions.

The only solution I see at the moment is to have two version of the help patch and then register the appropriate version in the setup function with "class_sethelpsymbol". However, this would be a maintenance nightmare. Also, the help patches would obviously need to have different names, so only one of them would match the name of the object.

Has anyone run into a similar situation? Any ideas?
