# Upstream has haphazard versioning: after going through “v1”-“v6”, they

# selected a version “final1”, and are now working on “final2”. They also keep

# all old versions in the git repository. We will package only based on the

# “final” version numbers. When “final2” is released, this package will move

# forward to that version, with “final1” offered in a parallel-installable

# compat package,

Version:        final1

%global common_description %{expand:

No hash function is perfect, but some are useful.

wyhash and wyrand are the ideal 64-bit hash function and PRNG respectively:

solid: wyhash passed SMHasher, wyrand passed BigCrush, practrand.

portable: 64-bit/32-bit system, big/little endian.

fastest: Efficient on 64-bit machines, especially for short keys.

simplest: In the sense of code size.}

# Since this is a header-only library, dependent packages must require one of

Dependent packages that require version %{version} in particular should use the

virtual Provides for %{compat_name}-devel/%{compat_name}-static, and should add

-I%{_includedir}/%{compat_name} to their compiler flags.
