+Cleaning Up Installed Files
+---------------------------
+
+There are few things we can do to improve our `build` makefile's `install`
+target.
+
+You may have noticed **oh-installfiles**(1) warn that something hasn't been
+installed:
+
+> oh-installfiles: Warning: Some files have not been installed into packages
+
+With **find**(1), we can see that this is the `libexpat.la` file that GNU
+libtool generated.
+
+    $ find tmp/dest -type f -exec ls -Fd '{}' ';' | sed 's|^tmp/dest||'
+    /usr/lib/core-linux-eglibc/libexpat.la*
+
+We don't need this, and we can simply delete it in the `install` target.
+
+Next, note that some file permissions aren't entirely correct.  For example,
+`libexpat.so.1.6.0` is executable, but almost all libraries need not be.
+
+So we can call **oh-fixperms**(1) in our `install` target to automatically set
+correct permissions for us.
+
+Finally, note that the executable and linkable objects are not stripped: they
+contain all of their symbols, including those only needed for debugging.
+
+    $ file tmp/libexpat.1.data/usr/lib/core-linux-eglibc/libexpat.so.1.6.0
+    tmp/libexpat.1.data/usr/lib/core-linux-eglibc/libexpat.so.1.6.0: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, BuildID[sha1]=0x2d88e36feeb8245bfa2f63f2f0e9a9f8232f6d2c, not stripped
+    $ file tmp/xmlwf.data/usr/bin/xmlwf
+    tmp/xmlwf.data/usr/bin/xmlwf: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.26, BuildID[sha1]=0xdb5f686930b13b8a5e7519efb446a2da14de9856, not stripped
+
+We can call **oh-strip**(1) in our `install` target to automatically strip
+objects for us.
+
+So our `build` makefile should now look like this:
+
+    #!/usr/bin/make -f
+    
+    nop:
+    	@:
+    
+    build:
+    	oh-autoconfigure
+    	oh-autobuild
+    	touch $@
+    
+    install: build
+    	oh-autoinstall
+    	rm -f 'dest/usr/lib/$(OPK_HOST_ARCH)/libexpat.la'
+    	oh-fixperms
+    	oh-strip
+    	oh-installfiles
+
