 Usage:
-  scripts/setup-dcmtk.sh [--source-dir DIR] [--install-dir DIR]
+  scripts/setup-dcmtk.sh [--source-dir DIR | --archive-url URL] [--install-dir DIR]
 
 Behavior:
   - Copies required DCMTK binaries into a local ignored directory.
   - If --source-dir is omitted, binaries are resolved from PATH.
+  - If --archive-url is given, the script downloads and extracts an archive,
+    then searches for the required binaries inside it.
 
 Examples:
   scripts/setup-dcmtk.sh --source-dir /opt/dcmtk/bin
+  scripts/setup-dcmtk.sh --archive-url https://github.com/<owner>/<repo>/releases/download/<tag>/dcmtk-bin.tar.gz
   scripts/setup-dcmtk.sh --install-dir /data/dcmtk-bin
