A good documentation makes a review of the program at a later date much easier. If somebody else has to review a program, the documentation will save much of the valuable time. The way programmers document programs reflects not only their personal programming style, it also becomes a reliable indication of their sense of discipline and organizational capabilities.

A simple definition relating to program documentation can be presented:

Their main arguments are that the paperwork is not worth the time, that it takes too long to collect all documents and prepare the documentation, that it is essentially a nonproductive effort, etc. These arguments are true, to a point - in order to make a good documentation, yes, some time will be required.
