+ <dt> <b>Why are the LLVM source code and the front-end distributed
+ under different licenses?</b>
+ <dd>
+ The C/C++ front-ends are based on GCC and must be distributed under
+ the GPL. Our aim is to distribute LLVM source code are a <em>much
+ less restrictive</em> license, in particular one that does not
+ compel users who distribute tools based on modifying the source to
+ redistribute the modified source code as well.
+
+ <dt><b>Does the Illinois Open Source License really qualify
+ as an "open source" license?</b>
+ <dd>The
+ <a href="http://www.opensource.org/licenses/UoI-NCSA.php">
+ UI Open Source License</a> is certified by the
+ Open Source Initiative (OSI).
+
+ <dt> <b>Can I modify LLVM source code and redistribute the modified
+ source?</b>
+ <dd>
+ Yes. The modified source distribution must retain notice both the
+ copyright notice and follow the three bulletted conditions listed in
+ the <a href="releases/1.0/LICENSE.txt">LLVM license</a>.
+
+ <dt> <b>Can I modify LLVM source code and redistribute binaries or
+ other tools based on it, without redistributing the source.
+ <dd>
+ Yes, this is why we distribute LLVM under a less restrictive license
+ than GPL, as explained in the first question above.
