"Libre", not "Libré"

[hishamhm]

The word does not take an accent in either Spanish or French.

(As a side note, the misspelling of "libre" and the participation of the OSI in the preparation of the survey does hint that the choice of using "open source" goes beyond mere "simplicity" as stated and suggests a closer affinity with one ideology over the other. The attempt at neutrality is still appreciated anyway.)
