+Building Everything
+-------------------
 
-TODO: Finish.
+Now we can build all of our source and binary packages and verify that
+everything is correct.
+
+**opkbuild**(1) maintains a cache file in the work area; because we've modified
+the metadata in our packaging since the first time we ran **opkbuild**(1), this
+cache file is out-of-date.  Also, we should make sure that the entire build
+process still works.  So let's clean up the work area before going any further.
+
+    $ rm -Rf tmp/
+
+Now let's run **opkbuild**(1) again, this time completely building all of our
+source and binary packages and cleaning up automatically when we're done.
+
+    $ opkbuild
+
+After that finishes, you should see the built packages in the parent directory.
+
+    $ ls -1 ../*.opk
+    ../libexpat.1_2.1.0-2_core-linux-eglibc_all.opk
+    ../libexpat.1-dev_2.1.0-2_core-linux-eglibc_all.opk
+    ../src-expat_2.1.0-2_src_all.opk
+    ../xmlwf_2.1.0-2_core-linux-eglibc_all.opk
+    ../xmlwf-doc_2.1.0-2_all_all.opk
+
+`src-expat` is a *source binary package* – a binary package installable with the
+package manager that provides the files in our source package.  This binary
+package is a convenient way to distribute our source package to others.
+
+You can use the **tar**(1) command to verify that the control information and
+data files in packages look correct.

+    Description: XML parser library
+     Expat is an XML parser library written in C. It is a stream-oriented parser in
+     which an application registers handlers for things the parser might find in the
+     XML document (like start tags).

+Congratulations!  You've made a source package that successfully builds four
+binary packages!
