Hi,

I pushed python-msgspec with changes to synopsis and description, but
then noticed that it contains an autogenerated C header (atof_consts.h)
which is generated by the script in /scripts. We probably should run
that script after the unpack phase but that should be done on a new
commit now.

+@item zero-cost schema validation using familiar Python type annotations.  In

+can decode it alone.
