+Changes Necessary
+=================
+
+See the SPF 2.0 specification for [a list of changes][spf-changes] introduced
+since SPF 1.0.
+
+These are the most common changes to update packages to SPF 2.0:
+
+  * Remove the old `Source` and `Version` [source package fields][spf-fields-s].
+  * Remove the old `Package` [binary package field][spf-fields-b].
+  * Add a `Platform` [binary package field][spf-fields-b] (usually with the
+    value "`all`".
+  * Rewrite [`build` makefiles][spf-build] to use the new `build` and `install`
+    targets.
+
+See the manual pages for opkhelper 3.0 utilities to learn more about their
+options.
+
+These are the most common changes to update packages to opkhelper 3.0 and to use
+multiarch library directories:
+
+  * Remove calls to obsolete opkhelper 1.0 utilities, e.g. `oh-installdocs`,
+    `oh-gencontrol`, and `oh-buildopk`.
+  * Update arguments given to opkhelper utilities.  `oh-installfiles` no longer
+    needs a list of packages, and `oh-strip` no longer needs a list of files.
+  * Use new `oh-auto*` build system utilities.
+  * Change commands like "`rm -f /usr/lib/lib….la`" to
+    "`rm -f /usr/lib/*/lib….la`".
+  * Rename `<binpkg>.pkg/install` to `<binpkg>.pkg/files`.
+  * Change "`/usr/lib/lib….so…`" patterns to "`/usr/lib/*/lib….so…`" in
+    `<binpkg>.pkg/files`.
+  * Add "`opkhelper-3.0`" to `Build-Depends`.
+
+Finally, add a [`changelog` entry][spf-changelog] documenting the changes.  Be
+sure to add "`trunk`" (the distribution) to the end of the first line of the new
+entry.  Also make sure the version identifier is [properly formed][spf-ver].
+Following is an example changelog entry (from [zlib][zlib-changelog]):
+
+    zlib (1.2.7+sip1-1) trunk
+    
+     * New upstream version.
+     * Update to SPF 2.0 and opkhelper 3.0.
+     * Use multiarch library directories.
+     * Don't distribute IETF RFCs (SIP compliance).
