%description
Lua 5.5 runtime packaged under a versioned library name for Fedora releases
that need a separately maintained Lua runtime. This package does not replace
the system Lua. Public C symbols use a private namespace so embedding it
does not interpose on Fedora libraries that use the native Lua ABI.
