%description
Lua is a powerful, light-weight programming language designed for
extending applications. It is also frequently used as a
general-purpose, stand-alone language. It combines simple procedural
syntax (similar to Pascal) with powerful data description constructs
based on associative arrays and extensible semantics. Lua is
dynamically typed, interpreted from bytecodes, and has automatic
memory management with garbage collection, making it ideal for
configuration, scripting, and rapid prototyping.

This version has compiled in support for dynamic libraries in baselib.

%description -l pl.UTF-8
Lua to język programowania o dużych możliwościach ale lekki,
przeznaczony do rozszerzania aplikacji. Jest też często używany jako
samodzielny język ogólnego przeznaczenia. Łączy prostą proceduralną
składnię (podobną do Pascala) z potężnymi konstrukcjami opisu danych
bazującymi na tablicach asocjacyjnych i rozszerzalnej składni. Lua ma
dynamiczny system typów, interpretowany z bytecodu i automatyczne
zarządzanie pamięcią z odśmiecaczem, co czyni go idealnym do
konfiguracji, skryptów i szybkich prototypów.

Ta wersja ma wkompilowaną obsługę ładowania dynamicznych bibliotek.
