Secondarily, this License preserves for the author and publisher a way to get credit for their work, while not being considered responsible for modifications made by others.</P ><P >This License is a kind of "copyleft", which means that derivative works of the document must themselves be free in the same sense. It complements the GNU General Public License, which is a copyleft license designed for free software.</P ><P >We have designed this License in order to use it for manuals for free software, because free software needs free documentation: a free program should come with manuals providing the same freedoms that the software does. But this License is not limited to software manuals; it can be used for any textual work, regardless of subject matter or whether it is published as a printed book. We recommend this License principally for works whose purpose is instruction or reference.</P ></DIV ><DIV CLASS="NAVFOOTER" ><HR ALIGN="LEFT" WIDTH="100%"><TABLE WIDTH="100%" BORDER="0" CELLPADDING="0" CELLSPACING="0" ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" ><A HREF="gfdl.html" >Prev</A ></TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="index.html" >Home</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" ><A HREF="gfdl-1.html" >Next</A ></TD ></TR ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" >GNU Free Documentation License</TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="gfdl.html" >Up</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" >APPLICABILITY AND DEFINITIONS</TD ></TR ></TABLE ></DIV ></BODY ></HTML >
