# Hyprland 0.55+ is configured in Lua 5.5; Fedora 44 only has Lua 5.4. This package installs
# 5.5 alongside it (versioned library, headers and pkg-config name), so nothing in Fedora
# that uses the system Lua is affected.

%description
Lua is a powerful, efficient, lightweight, embeddable scripting language. This package
provides Lua %{major_minor} as a versioned shared library (liblua-%{major_minor}.so) and the
lua%{major_minor} interpreter, without conflicting with the system Lua.
