(** The default value of [~mode] is the mode specified via the
command line (either to the melt tool or directly to the executable).
The [~file] parameter may be used if you want to specify the file name
used for the figure Metapost script. Otherwise, a default name is
chosen. This default name is [base.melt.figureN.ext], where [base] is
the executable base name (can be overriden with the [-name] option on
the command line), [N] is the figure index and [ext] is [mps] if
[-pdf] is [true] or [1] otherwise. *)
