+       <emphasis>runtime dependencies</emphasis>.
+       Build dependencies are packages that must be present at build time
+       in order to successfully build your source package. The act of building
+       your source package will create one or more binary packages. Each binary
+       package can specify some number of runtime dependencies (packages that
+       your software needs to be present at runtime), and the package
+       manager will try to install these together with your package.
+       Both types of dependencies - build and runtime - are specified in the
+       build recipe. Exactly how this is done is described in the documentation
+       of the build system (RPM, Debian, etc.) in question and is beyond the
+       scope of this &obs; documentation.
