GRFDiff(1) BSD General Commands Manual GRFDiff(1)
NAME
GRFDiff -- A tool to create a binary GRF diff from to GRFs.
SYNOPSIS
grfdiff [-hnxyv] [-l numbers] [-o GRF-File] Original-GRF-file New-GRF-file
Compare the two GRF files and produce a GRD file containing only the sprites from the second file that are different from the first
file.
GRFDiff makes a .GRD file with the same basename as the new GRF file.
OPTIONS
-h Display the help message.
-l numbers Save the sprites with these numbers in the .GRD instead of finding the modified sprites. With this option, the first GRF file
can be omitted.
Format of the numbers: <from1>[-<to1>][,<from2>[-<to2>]]... e.g. 1-5,8,20-31 (must be increasing numbers).
-n Only show a list of modified sprites, don't make a .GRF file.
-x Make a self-extracting (.EXE) file instead of a .GRD.
-y Answer 'y' to all questions.
-v Display the version.
You can specify several sets of GRF files along with their -l options by separating them with a double-dash `--'. The result will be written
to a single .GRD file. Only -l is valid after the first set.
