+build/svg-render 2.0
+
+Usage: build/svg-render [options]... [input_file] [output_file]
+
+Specify "-" for stdin/stdout.
+
+    -h, --help
+        Print help and exit
+    -v, --version
+        Print version and exit
+    -o, --format
+        Output format. Supported: gerber, svg, s-exp (KiCAD S-Expression)
+    -p, --precision
+        Number of decimal places use for exported coordinates (gerber: 1-9,
+        SVG: 0-*)
+    --clear-color
+        SVG color to use for "clear" areas (default: white)
+    --dark-color
+        SVG color to use for "dark" areas (default: black)
+    -d, --trace-space
+        Minimum feature size of elements in vectorized graphics
+        (trace/space) in mm. Default: 0.1mm.
+    --no-header
+        Do not export output format header/footer, only export the
+        primitives themselves
+    --flatten
+        Flatten output so it only consists of non-overlapping white
+        polygons. This perform composition at the vector level. Potentially slow.
+    --no-flatten
+        Disable automatic flattening for KiCAD S-Exp export
+    --dilate
+        Dilate output gerber primitives by this amount in mm. Used for
+        masking out other layers.
+    -g, --only-groups
+        Comma-separated list of group IDs to export.
+    -b, --vectorizer
+        Vectorizer to use for bitmap images. One of poisson-disc (default),
+        hex-grid, square-grid, binary-contours, dev-null.
+    --vectorizer-map
+        Map from image element id to vectorizer. Overrides --vectorizer.
+        Format: id1=vectorizer,id2=vectorizer,...
+    --force-svg
+        Force SVG input irrespective of file name
+    --force-png
+        Force bitmap graphics input irrespective of file name
+    -s, --size
+        Bitmap mode only: Physical size of output image in mm. Format: 12.34x56.78
+    --sexp-mod-name
+        Module name for KiCAD S-Exp output
+    --sexp-layer
+        Layer for KiCAD S-Exp output. Defaults to auto-detect layers from
+        SVG layer/top-level group names
+    -a, --preserve-aspect-ratio
+        Bitmap mode only: Preserve aspect ratio of image. Allowed values
+        are meet, slice. Can also parse full SVG preserveAspectRatio syntax.
+    --no-usvg
+        Do not preprocess input using usvg (do not use unless you know
+        *exactly* what you're doing)
+    -e, --exclude-groups
+        Comma-separated list of group IDs to exclude from export. Takes
+        precedence over --only-groups.
