# Support three arguments (this recommend but not required):
# -f <file> Execute file on host, print the result and exit
# -c <command> Execute command on host, print the result and exit
# -v <level> Verbose mode: 1 - verbose, 2 - super verbose
# -e <NAME=B64> -e ... Environement variables (B64 is base64 encoded string)

## Example disabling option:
#if [[ $EXECUTE_COMMAND ]]; then
# echo '<THIS> entrypoint is not support command execution.'
# exit 1
#fi
## Example command argument:
#if [[ $EXECUTE_COMMAND ]]; then
# EXECUTE_COMMAND=(-c "${EXECUTE_COMMAND}")
#fi
#
#if [[ $EXECUTE_FILE ]]; then
# EXECUTE_COMMAND=""
#fi
## Example of adding argument `-f` before
#EXECUTE_FILE=`[ $EXECUTE_FILE ] && echo -n "-f $EXECUTE_FILE" || echo -n ""`
#
#
# Move to current directory
#

#
# Run the portable shell
#
./your_portable_shell
# Example:
# ./your_portable_shell $EXECUTE_FILE "${EXECUTE_COMMAND[@]}"
