  +========================
   
   * Use shell functions, but be careful not to assume local scope for
     variable names.  Don't use `return', instead echo the result of a
     function and call it from within backquotes.
  +
  +* Function names should be prefixed `func_'.
  +
  +* For functions that are called frequently, if you need to return a
  +  value, don't cause unneccessary forking of the shell using echo as
  +  described above; instead set the return value in a variable named
  +  after the called function with a suffix of `_result'.  For example
  +  the function `func_quote_for_eval' stores its return value in the
  +  variable `$func_quote_for_eval_result'.
  +
  +* Although sh-indentation is set to 2 (by the `Local Variables:' block
  +  at the end of .m4sh files), the left margin of the body of shell
  +  functions should begin indented by 4 spaces.
