Requires: OS V2.0 (V37+)

WDelta is a program to create a differences file from two differnt binary
input files. The difference file (wdelta-file) can later be used to build
the second input file from the first and the wdelta file.

WDelta is released under the GPL, the source code is provided with this
package.

WDelta is able to replace scompare/spatch from the SAS-C development
package. Advantages are:
 - GPL
 - smaller differences files
 - creation and extraction in one single program


  SYNOPSIS

  to create a wdelta-file:
    wdelta c source-file destination-file wdelta-file [fc=n] [qc=m]

  to apply a wdelta-file:
    wdelta source-file destination-file wdelta-file

  OPTIONS
  
    c    - enables creation of wdelta file
    
    fc=n - amount of bytes to search further after a new sync has been found,
           maybe increased get smaller wdelta-files, maybe decreased for
           faster calculation on slower machines (68020/030), default is 180
           bytes
    
    qc=m - amount of bytes to use to calculate quality of found sync, should 
           not be changed, default is 18 bytes

  FURTHER INFORMATIONS
  
    WDelta is pure and can made resident.
    Creation of wdelta-files requires a 68020 or better, applying works on all
    m68k.
    WDelta-files contain a 16-bit crc for input, output and wdelta-files for
    secure operation.

  only useful comments are welcome ;)
    
  greetings to all my friends.
  thanks to the universe for being.

  in der kürze liegt die würze!
