+The dateparse\_utils.DateParser class uses an English language grammar
+(see dateparse\_utils.g4) to parse free form English text into a Python
+datetime. It can handle somewhat complex constructs such as: "20 days
+from next Wed at 3pm", "last Christmas", and "The 2nd Sunday in May,
+2022". See the dateparse_utils_test.py for more examples.
+
+This code is used by other code in the pyutils library; for example,
+when using argparse_utils.py to pass an argument of type datetime it
+allows the user to use free form english expressions.
