       If the first character  of  parameter  is  an  exclamation
       point,  a  level  of  variable  indirection is introduced.
       Bash uses the value of the variable formed from  the  rest
       of parameter as the name of the variable; this variable is
       then expanded and that value is used in the  rest  of  the
       substitution,  rather  than the value of parameter itself.
       This is known as indirect  expansion.   The  exception  to
       this is the expansion of ${!prefix*} described below.
