+  get_label_info(target_label, what)
+
+  Given the label of a target, returns some attribute of that target. The
+  target need not have been previously defined in the same file, since none of
+  the attributes depend on the actual target definition, only the label itself.
+
+  See also "gn help get_target_outputs".
+
+Possible values for the "what" parameter
+
+  "name"
+      The short name of the target. This will match the value of the
+      "target_name" variable inside that target's declaration. For the label
+      "//foo/bar:baz" this will return "baz".
+
+  "dir"
+      The directory containing the target's definition, with no slash at the
+      end. For the label "//foo/bar:baz" this will return "//foo/bar".
+
+  "target_gen_dir"
+      The generated file directory for the target. This will match the value of
+      the "target_gen_dir" variable when inside that target's declaration.
+
+  "root_gen_dir"
+      The root of the generated file tree for the target. This will match the
+      value of the "root_gen_dir" variable when inside that target's
+      declaration.
+
+  "target_out_dir
+      The output directory for the target. This will match the value of the
+      "target_out_dir" variable when inside that target's declaration.
+
+  "root_out_dir"
+      The root of the output file tree for the target. This will match the
+      value of the "root_out_dir" variable when inside that target's
+      declaration.
+
+  "label_no_toolchain"
+      The fully qualified version of this label, not including the toolchain.
+      For the input ":bar" it might return "//foo:bar".
+
+  "label_with_toolchain"
+      The fully qualified version of this label, including the toolchain. For
+      the input ":bar" it might return "//foo:bar(//toolchain:x64)".
+
+  "toolchain"
+      The label of the toolchain. This will match the value of the
+      "current_toolchain" variable when inside that target's declaration.
