Compilation flags:
`static`
Template:
`file_header(Stream,Identifier,Options)`
Mode and number of proofs:
`file_header(+stream_or_alias,+atom,+list(compound))` - `one`

### `file_footer/3`

Writes the output file footer using the specified options.

Compilation flags:
`static`
Template:
`file_footer(Stream,Identifier,Options)`
