Assume you develop a program that you were going to release to public. You develop it with aim to release it later under GPL license. Thus you add all those "NO WARRANTY" marks, and include a copyright and license notice to each file.
However, something happens that prevents you from releasing the project, so it just sleeps on your hard drive unmaintained and never sees the light.
GPL contains many clauses that govern propagation of software and creation of derived work. But I'm sure it imposes some implications on the work licensed.
In other words, does the software described above comply to GPL terms?
