- 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.
