Nitpick: normally, we place the arguments right below the
“build-system”.  The “native-inputs” then follow after “arguments”.

This synopsis is a bit long.  Maybe drop “efficient”?  (Most projects
include “efficient” or “fast” in their descriptions, so it isn’t very
useful in a synopsis.)

“A library”?  How about “This package provides a library implementing...”
