This is freeware. You can use this software without charges as long as you want and as long as it stays unchanged. Sensalgo Software License Agreement English Version: Sensalgo Software grants a license to use the enclosed software. Neither source code for Sensalgo Software products nor modified source code for Sensalgo Software products may be distributed under any circumstances, nor may you distribute .OBJ, .LIB, etc. files that contain our routines. If this is a component, it may be used as a constituent component only if the compound component thus created is distributed with and as an integral part of an application. Permission to use this freeware component as a constituent component does grant a right to distribute the license (LIC) file. This license may be transferred to a third party. This software is provided "as is". Sensalgo Software makes no warranty, expressed or implied, with regard to the software. All implied warranties, including the warranties of merchantability and fitness for a particular use, are hereby excluded. Sensalgo SOFTWARE'S LIABILITY IS LIMITED TO THE PURCHASE PRICE. Under no circumstances shall Sensalgo Software or the authors of this product be liable for any incidental or consequential damages, nor for any damages in excess of the original purchase price. To be eligible for free technical support via the Internet and to ensure that you are notified of any future updates, please complete the enclosed registration card and return it to Sensalgo Software. You may not change the product in any way that removes or changes the requirement of a license file. We encourage the use of our components as constituent components when the compound components you create are an integral part of your application. But we don't allow distribution of our components as constituents of other components when the compound component is not part of an application. The reason we need to have this restriction is that without it someone might decide to use our component as a constituent, add some trivial (or even non-trivial) enhancements and then sell the compound component. Obviously there would be little difference between that and just plain reselling our component. If you have purchased the source code, you may not re-distribute the source code either (nor may you copy it into your own project). Sensalgo Software retains the copyright to the source code. Contact us for further information. The freeware versions of our products are intended for commercial and non commercial purposes. You may use a components freeware version to develop complete applications. --------------------------------------------------------------- Copyright (c) Marc Blow Sensalgo-Soft Hamburg www.sensalgo.com
