PREAMBLEThe purpose of this License is to make a manual, textbook, or otherfunctional and useful document "free" in the sense of freedom: toassure everyone the effective freedom to copy and redistribute it,with or without modifying it, either commercially or noncommercially.Secondarily, this License preserves for the author and publisher a wayto get credit for their work, while not being considered responsiblefor modifications made by others.This License is a kind of "copyleft", which means that derivativeworks of the document must themselves be free in the same sense. Itcomplements the GNU General Public License, which is a copyleftlicense designed for free software.We have designed this License in order to use it for manuals for freesoftware, because free software needs free documentation: a freeprogram should come with manuals providing the same freedomsthat the software does. But this License is not limited to softwaremanuals; it can be used for any textual work, regardless of subjectmatter or whether it is published as a printed book. We recommendthis License principally for works whose purpose is instructionor reference.ANOTACIONES341
