### Configuration
#####################################################################
# Environment variables and their defaults
LOG_LEVEL="${LOG_LEVEL:-6}" # 7 = debug -> 0 = emergency
# Commandline options. This defines the usage page, and is used to parse cli
# opts & defaults from. The parsing is unforgiving so be precise in your syntax
read -r -d '' usage <<-'EOF'
-u [arg] URL to process. Required.
-f [arg] Certificate file to use.
-g Generates the necessary certificate.
-p Paste certificate from previous run.
-b Buys the associated domain name.
-i Configure OpenDKIM.
-c Configures DNS on Namecheap.
-d Enables debug mode

### Switches (like -d for debugmdoe, -h for showing helppage)
#####################################################################

fi
# help mode

### Validation (decide what's required for running your script and error out)
#####################################################################
[ -z "${arg_u}" ] && help "URL is required."
[ -z "${LOG_LEVEL}" ] && emergency "Cannot continue without LOG_LEVEL."
### Runtime
#####################################################################
# Exit on error. Append ||true if you expect an error.
# set -e is safer than #!/bin/bash -e because that is neutralised if
# someone runs your script like `bash yourscript.sh`
set -o errexit
set -o nounset
# Bash will remember & return the highest exitcode in a chain of pipes.
# This way you can catch the error in case mysqldump fails in `mysqldump |gzip`
