 ### Other executable scripts
-An execuatable script for a command named `extcmd` should be named `brew-extcmd`. The script itself can use any suitable shebang (`#!`) line, so an external script can be written in sh, bash, Ruby, or anything else. Unlike the ruby commands this file must not end with a language-specific suffix (`.sh`, or `.py`). This file will be run via `exec` with some Homebrew variables set as environment variables, and passed any additional command-line arguments.
