Ano, tak nejak je to zamyslene, ale momentalne to neni ve standardnim 
kernelu implementovane. Proste tento atribut je vyhrazen pro pouziti 
nekdy v budoucnu. Nicmene uz dnes existuje (pry) pomerne spolehliva 
implementace online komprese, i kdyz zatim v beta verzi - podivejte se 
na http://www.netspace.net.au/~reiter/e2compr.html.
