 <p>The first line defines rules to compile each source in <code>SOURCES</code>, using the
 flags in <code>CFLAGS</code>:</p>
 <pre class="prettyprint">
 $(foreach src,$(SOURCES),$(eval $(call COMPILE_RULE,$(src),$(CFLAGS))))
 </pre>
 <p>The next six lines define rules to link the object files into one or more
 executables. When <code>TOOLCHAIN</code> is <code>pnacl</code>, there is only one executable
 generated: in the example above, <code>part2.pexe</code>. When using a NaCl toolchain,
 there will be three executables generated, one for each architecture: in the
 example above, <code>part2_arm.nexe</code>, <code>part2_x86_32.nexe</code> and
 <code>part2_x86_64.nexe</code>.</p>
 <p>When <code>CONFIG</code> is <code>Release</code>, each executable is also stripped to remove
-debug information and reduce the file size:</p>
+debug information and reduce the file size. Otherwise, when the <code>TOOLCHAIN</code>
+is <code>pnacl</code>, the workflow involves creating an unstripped binary for debugging
+and then finalizing it and stripping it for publishing.</p>

 each executable generated in the previous step:</p>
