Здравствуйте.
Я научился программировать на lua. :)

Кто-нибудь сталкивался?  Язычок в принципе ничего.  Очень раздражает
отсутствие 'continue' в цикле (при том, что есть 'break').  Разработчики
языка не хотят добавлять continue по каким-то принципиальным
соображениям.  В результате вместо

	while ... do
		if ... then
			continue
		end
	end

приходится писать

	while ... do
		while true do
			if ... then
				break
			end
			break
		end
	end

Ну так вот.  Алгоритм оптимизации зависимостей в BuildRequires.
Происходит в два этапа: 1) expand: список зависимостей дополняется
настолько, насколько это возможно; 2) squeeze: список зависимостей
сжимается настолько, насколько это возможно.

Ниже приводится протокол выполнения алгоритма для списка пакетов
{ rpm-build, xvfb-run }.  На выходе получается тот же самый список (т.е.
эти пакеты между собой не зависят, а всё остальное успешно выносится.
Usage: ./squeeze.lua <список пакетов>.

Для сборки нужно librpm-devel, liblua5-devel, для запуска lua5.
