#! /bin/bash

usage="$(basename "$0") - Template for automatic creation of raw, blank scripts with given name and extension in provided directory - because who wants to type it by its own???!
        -d <dir> [current_dir] - directory for new file to be saved at
        -n <Any name> - name of a file in qoutes - any dots/lines will be removed and spaces replaces by underscores
        -e <extension> [cpp] - extension of a future file

    Enjoy!
