+Usage:
+    ./http_downloader.py <list_of_urls_filepath>
+
+Description:
+    The program was intended to work as a simple downloader of multiple http urls using wget. The URLs are
+    given in the first parameter of the program. Then it reads every line of the file and interprets it as
+    one URL. Each line is passed to wget to download.
