SoftwareSerial with ATTiny84 using ATtiny library

Hello Coding Badly,

I tried the KnockBang protocol, but I got the error message from the compiler :
warning: TinyDebugKnockBang.h: No such file or directory

I had copied before both files to the "library" folder.
Also copying them to the "hardware/cores/tiny" folder did not help.

Regards, Rudolf
