the name of your project.</li>
+<li>
+If you downloaded LLVM using CVS, remove all the directories named CVS (and all
+the files therein) from your project's new source tree. This will keep CVS
+from thinking that your project is inside <tt>llvm/projects/sample</tt>.

<li>Add your source code and Makefiles to your source tree.</li>
-<li>If you want your Makefiles to be configured by the <tt>configure</tt>
-script, or if you want to support multiple object directories, add your
-Makefiles to the <tt>configure</tt> script by adding them into the
-<tt>autoconf/configure.ac</tt> file. The macro <tt>AC_CONFIG_MAKEFILE</tt> will
-copy a file, unmodified, from the source directory to the object directory.</li>
+<li>If you want your project to be configured with the <tt>configure</tt> script
+then you need to edit <tt>autoconf/configure.ac</tt> as follows:
+ <ul>
+ <li><b>AC_INIT</b>. Place the name of your project, its version number and
+ a contact email address for your project as the arguments to this macro</li>
+ <li><b>AC_CONFIG_AUX_DIR</b>. If your project isn't in the
+ <tt>llvm/projects</tt> directory then you might need to adjust this so that
+ it specifies a relative path to the <tt>llvm/autoconf</tt> directory.</li>
+ <li><b>LLVM_CONFIG_PROJECT</b>. Just leave this alone.</li>
+ <li><b>AC_CONFIG_SRCDIR</b>. Specify a path to a file name that identifies
+ your project; or just leave it at <tt>Makefile.common.in</tt></li>
+ <li><b>AC_CONFIG_FILES</b>. Do not change.</li>
+ <li><b>AC_CONFIG_MAKEFILE</b>. Use one of these macros for each Makefile
+ that your project uses. This macro arranges for your makefiles to be copied
+ from the source directory, unmodified, to the build directory.</li>
+ </ul>
+</li>
<li>After updating <tt>autoconf/configure.ac</tt>, regenerate the
configure script with these commands:
<div class="doc_code">
<p><tt>% cd autoconf<br>
- % autoconf -o ../configure</tt></p>

+<p>You must be using Autoconf version 2.59 or later and your aclocal version
+should 1.9 or later.</p></li>
<li>Run <tt>configure</tt> in the directory in which you want to place
object code. Use the following options to tell your project where it
can find LLVM:
<dl>
- <dt><tt>--with-llvmsrc=<directory></tt>
- <dd>
- Tell your project where the LLVM source tree is located.
- <p>
- <dt><tt>--with-llvmobj=<directory></tt>

programs to test your code, gather statistics information, and
compare it to the current LLVM performance statistics.
