The author has coined a new word, EvALUEwARE, to describe a special type of software. He defines EvALUEwARE to be the full-featured product offered free -- as a marketing technique -- expecting satisfied users will purchase future versions.

The author recognizes that computer software holds a unique position in the publication universe. Computer software is easy to copy. Computer users often copy programs, unaware they may be violating copyright law. The author will not risk making his customers into unwitting criminals. Therefore, he permits users to copy and distribute freely. In fact, the software is available from bulletin board systems and software library distributors.

The author is so confident users will love the software, they will purchase the newest version. He thinks of this as a money-back guarantee before-the-fact.
