10			ASCII.  Joliet filenames are stored in Unicode format, but

12			There is also an option of doing UTF-8 translations with the
13			utf8 option.
14	  utf8          Encode Unicode names in UTF-8 format. Default is no.

18	  block=1024    Set the block size for the disk to 1024 bytes
19	  block=2048    Set the block size for the disk to 2048 bytes
20	  check=relaxed Matches filenames with different cases
21	  check=strict  Matches only filenames with the exact same case
22	  cruft         Try to handle badly formatted CDs.
23	  map=off       Do not map non-Rock Ridge filenames to lower case
24	  map=normal    Map non-Rock Ridge filenames to lower case
25	  map=acorn     As map=normal but also apply Acorn extensions if present
26	  mode=xxx      Sets the permissions on files to xxx unless Rock Ridge
27			extensions set the permissions otherwise
28	  dmode=xxx     Sets the permissions on directories to xxx unless Rock Ridge
29			extensions set the permissions otherwise
30	  overriderockperm Set permissions on files and directories according to
31			'mode' and 'dmode' even though Rock Ridge extensions are
32			present.
33	  nojoliet      Ignore Joliet extensions if they are present.
34	  norock        Ignore Rock Ridge extensions if they are present.
35	  hide		Completely strip hidden files from the file system.
36	  showassoc	Show files marked with the 'associated' bit
37	  unhide	Deprecated; showing hidden files is now default;
38			If given, it is a synonym for 'showassoc' which will
39			recreate previous unhide behavior
40	  session=x     Select number of session on multisession CD
41	  sbsector=xxx  Session begins from sector xxx
42	
43	Recommended documents about ISO 9660 standard are located at:
44	http://www.y-adagio.com/
45	ftp://ftp.ecma.ch/ecma-st/Ecma-119.pdf
46	Quoting from the PDF "This 2nd Edition of Standard ECMA-119 is technically 
47	identical with ISO 9660.", so it is a valid and gratis substitute of the
48	official ISO specification.
