What is Shareware?

Shareware distribution gives users a chance to try software before buying 
it. If you try a Shareware program and continue using it, you are expected 
to register. Individual programs differ on details -- some request 
registration while others require it, some specify a maximum trial period. 
With registration, you get anything from the simple right to continue using 
the software to an updated program with printed manual.

Copyright laws apply to both Shareware and commercial software, and the 
copyright holder retains all rights, with a few specific exceptions as 
stated below. Shareware authors are accomplished programmers, just like 
commercial authors, and the programs are of comparable quality. (In both 
cases, there are good programs and bad ones!) The main difference is in 
the method of distribution. The author specifically grants the right to 
copy and distribute the software, either to all and sundry or to a specific 
group. For example, some authors require written permission before a 
commercial disk vendor may copy their Shareware.

Shareware is a distribution method, not a type of software. You should find 
software that suits your needs and pocketbook, whether it's commercial or 
Shareware. The Shareware system makes fitting your needs easier, because 
you can try before you buy.  And because the overhead is low, prices are 
low also. Shareware has the ultimate money-back guarantee -- if you don't 
use the product, you don't pay for it.
