+version:         0.1.2.0
+synopsis:        A tool to prune unused symbols from icon SVG files.
+description:
+  This is a simple tool to prune unused symbols from icon SVG files.
+  Specifically, this tools takes as input
+  - an SVG file that consists only of `symbol` elements,
+  - one of more glob patterns of source files, and
+  - a regular expression that identifies symbol references.
+  It then scans your source files for references to symbols in the SVG
+  file. The output of the tool is an SVG file that contains only the
+  symbols referenced in your source files.
