@chapter convert-mudela
@code{convert-mudela} sequentially applies different
mudela-conversions to upgrade a Mudela input file.  It uses
@code{\version} statements in the file to detect the old version
number.

@example
        convert-mudela [options] [files]
@end example

@section Options
@table @samp
@item --output
    The output file to write.  
@item --edit
    Do an inline edit of the input file. override @code{--output}
@item --show-rules
    shows all known conversions, and exit
@item --from=@var{FROM_PATCHLEVEL}
    Set the level to convert from. If this is not set, convert-mudela will
    guess this, on the basis of @code{\version} strings in the file
@item --to=@var{TO_PATCHLEVEL}
    Set the goal version of the conversion. It defaults to the latest
    available version.
@end table

Not all language changes are handled. Multiple output options won't
work.
