"""
This Python script is used to programmatically delete incidents in batches of 100. 



The user must also have enabled Incident Deletion via the UI in
Administrator Settings -> Organization -> Settings -> Incident Deletion

HOW TO USE:
The basic command to run the deleteincidents.py script must include
user credentials with permission to delete the intended incidents. For example,
a Master Admin has permission to delete all incidents, so when
this script is run with Master Admin credentials all incidents will be
deleted. The usage structure for the command is as follows:

usage (to be run via the command line):
python deleteincidents.py [-h] --email EMAIL [--password PASSWORD] --host HOST
                          [--port PORT] [--proxy [PROXY [PROXY ...]]]
                          [--org ORG] [--cafile CAFILE] [--noverify]

arguments:
-h, --help            show this help message and exit

--email EMAIL         The email address to use to authenticate to the Resilient server.

--password PASSWORD   WARNING: This is an insecure option since the password
                      will be visible to other processes and stored in the
                      command history. The password to use to authenticate to
                      the Resilient server. If omitted, the you will be prompted.

--host HOST           Resilient server host name.

--port PORT           Resilient server REST API port number.

--proxy [PROXY [PROXY ...]]
                      An optional HTTP proxy to use when connecting.

--org ORG             The name of the organization to delete incidents from.

--cafile CAFILE       The name of a file that contains trusted certificates.

--noverify            Do not worry about verifying server certificates


This script can be run from any location that can connect to the Resilient
instance the user would like to delete incidents from.
