-When someone other than the usual maintainer releases a package they
-should add a new minor version number to the <var/debian-revision/ part of
-the version number (the portion after the last hyphen).
-This extra minor number will start at `1'. For example, consider
-the package `foo', which is at version 1.1-3. In the archive, the source
-package control file would be <tt>foo_1.1-3.dsc</tt>. The upstream
-version is `1.1' and the Debian revision is `3'. The next NMU would
-add a new minor number `.1' to the Debian revision; the new source
-control file would be <tt>foo_1.1-3.1.dsc</tt>.

+This section applies to NMUs, but not, necessarily, to porters.
+A distinction is made between a <em/port/ and an <em/NMU/. An NMU is
+a fix to a problem with an existing version of a package in an
+archive. A port is a recompile of a specific revision of a package to
+another port, such that people running the target architecture have
+access to the port.
+ <p>
+The following applies to porters insofar as they are playing the dual
+role of being both NMU bug-fixers, and porters. So, if a porter has
+to change the Debian source archive, automatically their upload is an
+NMU and is subject to its rule. If a porter is simply uploading a
+port, the rules are different; see <ref id="porter-guiddelines">.

+ <p>
+Whenever you have made a change to a package, no matter
+how trivial, the version number needs to change. This enables our
+packing system to actually work.
+ <p>
+If you are doing a non-maintainer upload (NMU), you should add a new
+minor version number to the <var/debian-revision/ part of the version
+number (the portion after the last hyphen). This extra minor number
+will start at `1'. For example, consider the package `foo', which is
+at version 1.1-3. In the archive, the source package control file
+would be <tt>foo_1.1-3.dsc</tt>. The upstream version is `1.1' and
+the Debian revision is `3'. The next NMU would add a new minor number
+`.1' to the Debian revision; the new source control file would be
+<tt>foo_1.1-3.1.dsc</tt>.
