<fileformat> controls the output format to be generated. Possible formats are: ASCII, HTML, (La)TeX, PDF, Postscript, DocBook... If the specified format is not supported by the executing software, or the <fileformat> statement is missing respectively, output is generated in ASCII format.
Specifying the output format determines also the file extension (see also <filename>):
