 | 	  This is the standard file system used on CD-ROMs.  It was previously | 
 | 	  known as "High Sierra File System" and is called "hsfs" on other | 
 | 	  Unix systems.  The so-called Rock-Ridge extensions which allow for | 
 | 	  long Unix filenames and symbolic links are also supported by this | 
 | 	  driver.  If you have a CD-ROM drive and want to do more with it than | 
 | 	  just listen to audio CDs and watch its LEDs, say Y (and read | 
 | 	  <file:Documentation/filesystems/isofs.rst> and the CD-ROM-HOWTO, | 
 | 	  available from <http://www.tldp.org/docs.html#howto>), thereby | 
 | 	  enlarging your kernel by about 27 KB; otherwise say N. | 
 |  | 
 | 	  To compile this file system support as a module, choose M here: the | 
 | 	  module will be called isofs. |

 | 	  Joliet is a Microsoft extension for the ISO 9660 CD-ROM file system | 
 | 	  which allows for long filenames in unicode format (unicode is the | 
 | 	  new 16 bit character code, successor to ASCII, which encodes the | 
 | 	  characters of almost all languages of the world; see | 
 | 	  <http://www.unicode.org/> for more information).  Say Y here if you |

 | 	  This is a Linux-specific extension to RockRidge which lets you store | 
 | 	  data in compressed form on a CD-ROM and have it transparently | 
 | 	  decompressed when the CD-ROM is accessed.  See | 
 | 	  <http://www.kernel.org/pub/linux/utils/fs/zisofs/> for the tools | 
 | 	  necessary to create such a filesystem.  Say Y here if you want to be | 
 | 	  able to read such compressed CD-ROMs. |
