NAME

4     GRFDiff — A tool to create a binary GRF diff from to GRFs.
5

SYNOPSIS

7     grfdiff [-hnxyv] [-l numbers] [-o GRF‐File] Original‐GRF‐file
8             New‐GRF‐file
9
10             Compare the two GRF files and produce a GRD file containing only
11             the sprites from the second file that are different from the
12             first file.
13
14             GRFDiff makes a .GRD file with the same basename as the new GRF
15             file.

OPTIONS

18     -h          Display the help message.
19
20     -l numbers  Save the sprites with these numbers in the .GRD instead of
21                 finding the modified sprites.  With this option, the first
22                 GRF file can be omitted.
23
24                 Format of the numbers: <from1>[‐<to1>][,<from2>[‐<to2>]]...
25                 e.g.  1‐5,8,20‐31 (must be increasing numbers).
26
27     -n          Only show a list of modified sprites, don't make a .GRF file.
28
29     -x          Make a self‐extracting (.EXE) file instead of a .GRD.
30
31     -y          Answer 'y' to all questions.
32
33     -v          Display the version.
34
35     You can specify several sets of GRF files along with their -l options by
36     separating them with a double‐dash `--'.  The result will be written to a
37     single .GRD file.  Only -l is valid after the first set.
