+# AutoTrace — convert bitmap raster images to vector graphics.
+#
+# CLI tool + libautotrace library. Same role as homebrew's
+# `autotrace` formula; closes pkgxdev/pantry#9454.
+#
+# Mandatory deps per upstream configure.ac:
+# - glib >= 2.44 (gmodule, gthread, gobject sub-libs)
+# - libpng (for PNG output)
+# - ImageMagick 7 (libMagickWand-7 for input formats)
+#
+# Optional features dropped to keep the bottle simple:
+# - pstoedit (no pantry recipe; would gain .ps / .eps output)
+# - graphicsmagick (alternate to ImageMagick — pick one)
