  In return for your support you will receive the very latest edition of    
 this manual on a disk, plus two disks of appendices, references and sample 
 source code. That's about two megabytes of raw data when uncompressed, or  
 the equivalent of ten manuals the size of the technical reference manuals  
 from IBM or Microsoft.                                                     
                                                                            
  In addition, supporting users may obtain updates by merely mailing a disk 
 and return postage. Significant changes will probably accumulate over the  
 course of a couple of months.
