+"""Generates a list of all files in a directory

[yzshen1, 2017/03/27 00:29:17]

style nit: trailing ".", please.

+
+This script takes in a directory and an output file name as input.
+It then reads the directory and creates a list of all file names
+in that directory.  The list is written to the output file.
+There is also an option to pass in '-p' or '--pattern'
+which will check each file name against a regular expression
+pattern that is passed in.  Only files which match the regex
+will be written to the list.
