+ <sect1 id="packages-arch-specific">When your package is <em>not</em> portable
+ <p>
+Some packages still have issues with building and/or working on some
+of the architectures supported by Debian, and cannot be ported at all,
+or not within a reasonable amount of time. An example is a package that
+is SVGA-specific (only i386), or uses other hardware-specific features
+not supported on all architectures.
+ <p>
+In order to prevent broken packages from being uploaded to the archive, and
+wasting buildd time, you need to do a few things:
+ <p>
+ <list>
+ <item>
+ <p>
+First, make sure your package <em>does</em> fail to build on
+architectures that it cannot support.
+There are a few ways to achieve this.
+The preferred way is to have a small testsuite during build time
+that will test the functionality, and fail if it doesn't work.
+This is a good idea anyway,
+as this will prevent (some) broken uploads on all architectures,
+and also will allow the package to build
+as soon as the required functionality is available.
+ <p>
+Additionally, if you believe the list of supported architectures is
+pretty constant, you should change 'any' to a list of supported
+architectures in debian/control. This way, the build will fail also,
+and indicate this to a human reader without actually trying.
+ <item>
+ <p>
+In order to prevent autobuilders from needlessly trying to build your
+package, it must be included in <file>packages-arch-specific</file>, a
+list used by the <prgn>wanna-build</prgn> script.
+The current version is available as
+<url id="http://cvs.debian.org/srcdep/Packages-arch-specific?cvsroot=dak">;
+please see the top of the file for whom to contact for changes.
+ </list>
+ <p>
+Please note that it is insufficient to only add your package to
+Packages-arch-specific
+without making it fail to build on unsupported architectures:
+A porter or any other person trying to build your package might
+accidently upload it without noticing it doesn't work.
+If in the past some binary packages were uploaded on unsupported architectures,
+request their removal by filing a bug against
+<package>ftp.debian.org</package>
