"""
Logging utility for logging to CloudWatch Logs, to use in e.g. AWS Lambda.

Some small features included:
- log structured JSON as that works really well with CloudWatch Logs filters and CloudWatch Logs Insights
- support turning any Python object into JSON
- replace line endings for nice folding of entries in CloudWatch Logs
- do not buffer stdout

"""
Usage:
 - Save this script somewhere on your path (e.g. `vi /usr/local/bin/aws-console && chmod +x /usr/local/bin/aws-console`)
 - Make AWS credentials available in one of the usual places where boto3 can find them (~/.aws/credentials, env var, etc.)
 - Excute the script: `aws-console --profile myprofile`
 - :tada: Your browser opens and you are signed in into the AWS console
