Note: This section was originally scaffolded for Dialog Box use. Later, it was leveraged to provide a basic help message. To avoid breaking functionality,
see module_cockpit or module_webmin

Propose: something for option "help" to always displays all while option "menu" conditionally filters based on $condition for use with the UX

help_message="Available commands:"

if [[ ($1 == "menu" && -z "$condition") || $1 == "help" ]]; then
    help_message+="\n\tinstall\t- Install $title."
fi
if [[ ($1 == "menu" && -n "$condition") || $1 == "help" ]]; then
    help_message+="\n\tremove\t- Remove $title."
    help_message+="\n\tpurge\t- Purge $title data folder."
    help_message+="\n\tstatus\t- Installation status $title."
fi

echo -e "$help_message"

if [[ $1 == "help" ]]; then
    echo -e "\nAvailable switches:\n"
    echo -e "\tpostgres_user\t\t- username."
    echo -e "\tpostgres_password\t- password."
    echo -e "\tpostgres_db\t\t- database name."
fi
