=======================================
Conditions of use and terms of warranty 
=======================================

§ 1: Concluding the contract

Opening the sealed plastic cover binds the end user to the conditions
of use and the terms of the warranty. If the end user does not wish to
be bound by these conditions, he should return the unopened package to
his supplier or to Springer-Verlag and the selling price will be refunded.
For the return of goods, § 7. is valid.


§ 2: Copyright and conditions of use

1. All rights pertaining to the Software (program and source code) are
   owned by the author. The Software is protected by copyright.

2. Springer-Verlag grants the end user, subject to legal liability, the
   non-exclusive right to use the Software as described by the terms of 
   this contract. Under this contract use of the program is restricted to
   that carried out according to the instructions described. The decompiling,
   disassembling, reverse engineering or in any way changing the program is
   expressly forbidden.

3. The program may, at any one time, only be used on one computer at 
   a single workplace. When used on computers with several or many terminals
   or in a network, a license application must be made for each workstation 
   or terminal on which use is possible.

4. The program may be copied once for backup purposes. 


§ 3: Transfer of the Software

1. Any transfer (e.g. sale) of the Software to a third party and with it the
   transfer of the right and the possibility of its use may only occur with
   the written permission of Springer-Verlag or the author.

2. Springer-Verlag will give this permission when the end user up to this 
   point makes a written application and the subsequent end user makes 
   a declaration that he will remain bound by the terms of this contract.
   Receipt of permission terminates the right of the first end user to operate
   the program and the transfer to the second end user may take place.


§ 4: Unauthorized use

1. The complete Software is protected by
	- the laws of copyright
	- the laws governing the use of trademarks
	- the laws of trade and commerce
	- this contract.
Violations may lead to action being taken under civil and criminal law.

2. The buyer is liable to Springer-Verlag for any damages or detriment accruing
   from any infringement of these regulations.


§ 5: Functional limitations of the Software

1. Even with the lates state of technological development and with meticulous care 
   being taken during production, errors in the Software cannot be excluded.

2. The Software evaluates and visualizes data.

3. The hardware and basis software described in the book are necessary for the 
   functional capability of the program. The installation of the Software must 
   be carried out exactly as described in the instructions. Deviation from these 
   instructions can lead to damage of the hardware and also to other software and 
   data.


§ 6: Warranty

1. In response to justified claims, Springer-Verlag has, as first possibility, 
   the option of supplying the user with another copy of the program (including 
   another program release). If the claim is still not remedied, the end user 
   can demand the return of the selling price from his supplier when he returns 
   the Software in compliance with the terms set out in § 7.

2. A prerequisite to making a claim under the warranty is that the end user supplies 
   an exact description of the defect in writing.

3. The end user has no claim to a reduction in the selling price or to correction 
   of defects. In other respects the German Code of Civil Law (BGB) concerning 
   the warranty of goods shall apply (§§ 459 to 480 BGB).


§ 7: Returning the software

1. The customer can only return the Software (e.g. according to § 1 or § 6 Sect. 1.)
   in its entirety together with the original sales receipt/invoice. In addition 
   he has to hand over the declaration stating that no copies remain in his possession.



§ 8: Help

1. Springer-Verlag has inaugurated the possibility of asking the author questions 
   with reference to the Software. However, this is a voluntary service and is not 
   the customer's right.

2. The questions can be concerned with installation, operation, and problems of 
   utilization. 

3. Questions should be mailed or sent via mailbox to Springer-Verlag (see handbook 
   for instructions). The answers from the author are merely forwarded by 
   Springer-Verlag without being checked. The questions are normally answered in 
   the order they are received. It will not be possible to answer every question.


§ 9: Liability

1. Springer-Verlag and the author are only liable for willful intent, gross 
   negligence, and when the program fails to fulfill its assured purpose and 
   function. The assured purpose and functions are those which are explicitly 
   declared in writing. There is no liability for information described in § 8.

2. The liability under German law for product liability is unaffected.

3. The plea that the end user is also at fault remains an option for Springer-Verlag.


§ 10: Conclusion

1. The location of the competent court for all legal action in connection with 
   the Software and this contract is D-69115 Heidelberg if the contract partner 
   is a registered trader or equivalent, or if he has no legal domicile in Germany.

2. This contract is exclusively governed by the laws of the Federal republic of 
   Germany with the exception of the UNCITRAL laws of trade and commerce.

3. Should any provision of the contract prove unenforceable or if the contract 
   is incomplete, the remaining provisions will remain unaffected. The invalid 
   provision shall be deemed replaced by the provision which in a legally binding 
   manner comes nearest in its meaning and purpose to the unenforceable provision. 
   This shall apply to any omission in the contract that may occur.
