From d62fe7c9bc2df6a4464440a3cae0539074bf99aa Mon Sep 17 00:00:00 2001 From: Paul Eggleton Date: Tue, 22 Dec 2015 17:02:54 +1300 Subject: scripts: print usage in argparse-using scripts when a command-line error occurs For scripts that use Python's standard argparse module to parse command-line arguments, create a subclass which will show the usage the usage information when a command-line parsing error occurs. The most common case would be when the script is run with no arguments; at least then the user immediately gets to see what arguments they might need to pass instead of just an error message.
