Usage

# Show help
MemoryPackDumper.exe --help

# Generate MemoryPack classes (single file)
MemoryPackDumper.exe --dummy-dll "path/to/dummydll"

# Specify output file
MemoryPackDumper.exe --dummy-dll "path/to/dummydll" --output-file "MemoryPack.cs"

# Split classes into individual files organized by namespace, output-file will now make a folder
MemoryPackDumper.exe --dummy-dll "path/to/dummydll" --split-class --output-file "./output"

# Split with custom root namespace
MemoryPackDumper.exe --dummy-dll "path/to/dummydll" --split-class --namespace "MyGame" --output-file "./output"

# Split with no root namespace (use original namespaces only)
MemoryPackDumper.exe --dummy-dll "path/to/dummydll" --split-class --namespace "" --output-file "./output"
