# ========= OPTIONS ==================
URL="https://github.com"
SCRIPT_URL="${URL}/jayp76/MiSTer_get_optional_installers/blob/master/yarmus_app.sh"
CURL_RETRY="--connect-timeout 15 --max-time 120 --retry 3 --retry-delay 5 --silent --show-error"

SCRIPTS_PATH="/media/fat/Scripts"

# ========= ADVANCED OPTIONS =========
# ALLOW_INSECURE_SSL="true" will check if SSL certificate verification (see https://curl.haxx.se/docs/sslcerts.html )
# is working (CA certificates installed) and when it's working it will use this feature for safe curl HTTPS downloads,
# otherwise it will use --insecure option for disabling SSL certificate verification.
# If CA certificates aren't installed it's advised to install them (i.e. using security_fixes.sh).
# ALLOW_INSECURE_SSL="false" will never use --insecure option and if CA certificates aren't installed
# any download will fail.
