+"""
+Find the location of one or more filenames, and output them to
+stdout. The search can be anchored within a directory using the --root
+parameter. By default, all matching paths (for all arguments) will be
+output. However, if the --single flag is set, only the first path
+found will be output.
+
+Examples:
+
+$ ./find_file_paths --root /bin -s mv
+
+  /bin/mv
+
+
+$ ./find_file_paths --root /bin mv ls
+
+  /bin/mv
+  /bin/ls
