+SVMClassifier Installation Script
+
+Usage: $0 [OPTIONS]
+
+OPTIONS:
+    -h, --help              Show this help message
+    -b, --build-type TYPE   Build type: Release, Debug, RelWithDebInfo (default: Release)
+    -p, --prefix PATH       Installation prefix (default: /usr/local)
+    -j, --jobs NUM          Number of parallel jobs (default: $(nproc))
+    -t, --torch-version VER PyTorch version to download (default: 2.7.1)
+    --skip-tests            Skip running tests after build
+    --clean                 Clean build directory before building
+    -v, --verbose           Enable verbose output
+
+EXAMPLES:
+    $0                                  # Install with default settings
+    $0 --build-type Debug --skip-tests  # Debug build without tests
+    $0 --prefix ~/.local                # Install to user directory
+    $0 --clean -v                       # Clean build with verbose output
+
+DEPENDENCIES:
+    The script will check for and help install required dependencies:
+    - CMake 3.15+
+    - C++17 compatible compiler (GCC 7+ or Clang 5+)
+    - PyTorch C++ (libtorch) - will be downloaded automatically
+    - Git (for fetching dependencies)
