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.
