+  get_path_info(input, what)
+
+  The first argument is either a string representing a file or directory name,
+  or a list of such strings. If the input is a list the return value will be a
+  list containing the result of applying the rule to each item in the input.
+
+Possible values for the "what" parameter
+
+  "file"
+      The substring after the last slash in the path, including the name and
+      extension. If the input ends in a slash, the empty string will be
+      returned.
+        "foo/bar.txt" => "bar.txt"

+        "foo/" => ""
+        "" => ""
+
+  "name"
+     The substring of the file name not including the extension.
+        "foo/bar.txt" => "bar"
+        "foo/bar" => "bar"
+        "foo/" => ""
+
+  "extension"
+      The substring following the last period following the last slash, or the

+        "foo/bar.txt" => "txt"
+        "foo/bar" => ""

+        "//foo/bar" => "//foo"
+        "foo" => "."
+
+      The result will never end in a slash, so if the resulting is empty, the
+      system ("/") or source ("//") roots, a "." will be appended such that it
+      is always legal to append a slash and a filename and get a valid path.
+
+  "out_dir"
+      The output file directory corresponding to the path of the given file,
+      not including a trailing slash.
+        "//foo/bar/baz.txt" => "//out/Default/obj/foo/bar"
+

+        "//foo/bar/baz.txt" => "//out/Default/gen/foo/bar"
+
+  "abspath"
+      The full absolute path name to the file or directory. It will be resolved
+      relative to the current directory, and then the source- absolute version
+      will be returned. If the input is system- absolute, the same input will
