Software considered as mature.
Fixed part Edit
The program must be either an old proven project, or a new one, with intensive testing in order to be sure there are no more important bugs.
The documentation should be very complete and the software should be integrated in distributions when applicable.
Flexible part Edit
The program is used in more or less production environements. It can be installed on a mature platform that is known as a modern one. If you apply strict, then you cannot use programs that run only on old platforms like MS DOS. You must choose a program that run on at least kernels, like Windo NT(kernel) and/or the linux kernel, etc...
Recomanded part Edit
It is best if the program have many or all of the features modern programs of his kind have.
