To summarize (a lot!), it means you can use DNSdoctor freely (but not
to link it with software which is not GPL-compatible), you can have 
the source code, you can distribute it freely (even after modifications)
BUT you cannot deny these freedoms to the people who receive it: for
instance, you must provide them with the source code.
