+  <title>&GetBuildPath;: Getting the Path From a &Node; or String</title>
+
+    <para>
+
+    <function>env.GetBuildPath(file_or_list)</function>
+    returns the path of a &Node; or a string representing a
+    path.  It can also take a list of &Node;s and/or strings, and
+    returns the list of paths.  If passed a single &Node;, the result
+    is the same as calling <literal>str(node)</literal> (see above).
+    The string(s) can have embedded construction variables, which are
+    expanded as usual, using the calling environment's set of
+    variables.  The paths can be files or directories, and do not have
+    to exist.

+
+    There is also a function version of &GetBuildPath; which can
+    be called without an &Environment;; that uses the default SCons
+    &Environment; to do substitution on any string arguments.
