Re: [Pharo-dev] [sbe] Pharo por Ejemplo vs Pharo en exemplos

by Esteban Lorenzano

Pharo by example is correctly translated to "Pharo a travÃ©s de ejemplos", but that sounds odd for marketing in spanish... I think the best translation would be "Pharo en ejemplos", but I will ask a friend of mine who is translator :) On May 21, 2013, at 4:05 PM, GastÃ³n Dall' Oglio <gaston.dalloglio(a)gmail.com> wrote: > Hello. > > Or "Pharo con ejemplos"? in my poor English, I always interpreted this way in Spanish. > > Regards. > > > 2013/5/21 Esteban A.

you cannot, once you commited, your package belong to the universe :) nah, it is a known missing feature (and really needed), there is a fix coming I think next week.
