from: http://www.gnu.org/software/bash/manual/bashref.html#shell-functions
functions declared using syntax:
name () compound-command [ redirections ] or function name [()] compound-command [ redirections ]
this defines shell function named name. the reserved word function optional. if function reserved word supplied, parentheses optional.
