+@section Automatic dependency tracking
+
+As a developer it is often onerous to continually update the
+@file{Makefile.in} whenever the include-file dependencies change in a
+project.  @code{automake} supplies a way to automatically track
+dependency changes, and distribute the dependencies in the generated
+@file{Makefile.in}.
+
+Currently this support requires the use of @code{GNU make} and
+@code{gcc}.  It might become possible in the future to supply a
+different dependency generating program, if there is enough demand.
+
+In order to use this mode, when developing your package, always run
+@code{automake} with the @samp{--use-deps} option.  This will cause
+dependency generating code to be inserted into your @file{Makefile.in}.
+
+When you decide to make a distribution, the @samp{dist} target will
+re-run @code{automake} with the @samp{--include-deps} option.  This
+causes the previously generated dependencies to be inserted into the
+generated @file{Makefile.in}, and thus into the distribution.
+
+The interface here might change as well.  In particular, dependency
+generation might become the default.
