   * <pre>
   * A description of a toolchain, which includes all the tools generally expected
   * to be available for building C/C++ targets, based on the GNU C compiler.
   * System and cpu names are two overlapping concepts, which need to be both
   * supported at this time. The cpu name is the blaze command-line name for the
   * target system. The most common values are 'k8' and 'piii'. The system name is
   * a more generic identification of the executable system, based on the names
   * used by the GNU C compiler.
   * Typically, the system name contains an identifier for the cpu (e.g. x86_64 or
   * alpha), an identifier for the machine (e.g. pc, or unknown), and an
   * identifier for the operating system (e.g. cygwin or linux-gnu). Typical
   * examples are 'x86_64-unknown-linux-gnu' and 'i686-unknown-cygwin'.
   * The system name is used to determine if a given machine can execute a given
   * exectuable. In particular, it is used to check if the compilation products of
   * a toolchain can run on the host machine.

     * <pre>
     * A group of correlated flags. Supports parametrization via variable
     * expansion.
     * To expand a variable of list type, flag_group has to be annotated with
     * `iterate_over` message. Then all nested flags or flag_groups will be
     * expanded repeatedly for each element of the list.
     * For example:
     * flag_group {
     *   iterate_over: 'include_path'
     *   flag: '-I'
     *   flag: '%{include_path}'
     * }
     * ... will get expanded to -I /to/path1 -I /to/path2 ... for each
     * include_path /to/pathN.
     * To expand a variable of structure type, use dot-notation, e.g.:
     *    flag_group {
     *      iterate_over: "libraries_to_link"
     *      flag_group {
     *        iterate_over: "libraries_to_link.libraries"
     *        flag: "-L%{libraries_to_link.libraries.directory}"
     *      }
     *    }
     * Flag groups can be nested; if they are, the flag group must only contain
     * other flag groups (no flags) so the order is unambiguously specified.
     * In order to expand a variable of nested lists, 'iterate_over' can be used.
     * For example:
     * flag_group {
     *   iterate_over: 'object_files'
     *   flag_group { flag: '--start-lib' }
     *   flag_group {
     *     iterate_over: 'object_files'
     *     flag: '%{object_files}'
     *   }
     *   flag_group { flag: '--end-lib' }
     * }
     * ... will get expanded to
     *   --start-lib a1.o a2.o ... --end-lib --start-lib b1.o b2.o .. --end-lib
     *   with %{object_files} being a variable of nested list type
     *   [['a1.o', 'a2.o', ...], ['b1.o', 'b2.o', ...], ...].
     * TODO(bazel-team): Write more elaborate documentation and add a link to it.
     * </pre>

       * <pre>
       * A group of correlated flags. Supports parametrization via variable
       * expansion.
       * To expand a variable of list type, flag_group has to be annotated with
       * `iterate_over` message. Then all nested flags or flag_groups will be
       * expanded repeatedly for each element of the list.
       * For example:
       * flag_group {
       *   iterate_over: 'include_path'
       *   flag: '-I'
       *   flag: '%{include_path}'
       * }
       * ... will get expanded to -I /to/path1 -I /to/path2 ... for each
       * include_path /to/pathN.
       * To expand a variable of structure type, use dot-notation, e.g.:
       *    flag_group {
       *      iterate_over: "libraries_to_link"
       *      flag_group {
       *        iterate_over: "libraries_to_link.libraries"
       *        flag: "-L%{libraries_to_link.libraries.directory}"
       *      }
       *    }
       * Flag groups can be nested; if they are, the flag group must only contain
       * other flag groups (no flags) so the order is unambiguously specified.
       * In order to expand a variable of nested lists, 'iterate_over' can be used.
       * For example:
       * flag_group {
       *   iterate_over: 'object_files'
       *   flag_group { flag: '--start-lib' }
       *   flag_group {
       *     iterate_over: 'object_files'
       *     flag: '%{object_files}'
       *   }
       *   flag_group { flag: '--end-lib' }
       * }
       * ... will get expanded to
       *   --start-lib a1.o a2.o ... --end-lib --start-lib b1.o b2.o .. --end-lib
       *   with %{object_files} being a variable of nested list type
       *   [['a1.o', 'a2.o', ...], ['b1.o', 'b2.o', ...], ...].
       * TODO(bazel-team): Write more elaborate documentation and add a link to it.
       * </pre>

       * An action config corresponds to a blaze action, and allows selection of
       * a tool based on activated features.  Action configs come in two varieties:
       * automatic (the blaze action will exist whether or not the action config
       * is activated) and attachable (the blaze action will be added to the
       * action graph only if the action config is activated).
       * Action config activation occurs by the same semantics as features: a
       * feature can 'require' or 'imply' an action config in the same way that it
       * would another feature.

     * <pre>
     * A description of a toolchain, which includes all the tools generally expected
     * to be available for building C/C++ targets, based on the GNU C compiler.
     * System and cpu names are two overlapping concepts, which need to be both
     * supported at this time. The cpu name is the blaze command-line name for the
     * target system. The most common values are 'k8' and 'piii'. The system name is
     * a more generic identification of the executable system, based on the names
     * used by the GNU C compiler.
     * Typically, the system name contains an identifier for the cpu (e.g. x86_64 or
     * alpha), an identifier for the machine (e.g. pc, or unknown), and an
     * identifier for the operating system (e.g. cygwin or linux-gnu). Typical
     * examples are 'x86_64-unknown-linux-gnu' and 'i686-unknown-cygwin'.
     * The system name is used to determine if a given machine can execute a given
     * exectuable. In particular, it is used to check if the compilation products of
     * a toolchain can run on the host machine.
     * </pre>
     *
