  echo "   -c, --case     Perform a case-sensitive search (Default is insensitive)."
  echo "   -h, --help     Show this help screen."

  echo " Notes "
  echo "======="
  echo " * Use any number of search terms, in any order."
  echo " * Search terms are not case sensitive, and order is irrelevant."
  echo "   * Use '-c' if you wish to reduce results by case-sensitive searching."
  echo " * Use '-t' to exclude the file's path to filter the search results."
  echo "   * Could possibly remove false positives (especially when searching numbers)."
  echo " * When updating from git or displaying help, search terms will be ignored."
