       pip - CD-ROM workbench


       Pip  is	a  SCSI  I/O program centered around a SCSI disk of files called tracks.  Various
       commands will load and store tracks from and  to  various  CD-ROM  readers,  writers,  and
       files.	Pip was written to be run on a stand-alone workstation so that the I/O data rates
       required for CD-audio can be sustained.

       When pip starts, it probes the SCSI bus and looks for one of the following disks.  The ta-
       ble in the program should be extended to include your favorite disk.  The program does not
       recognize just any disk because it might scribble on precious data.

       Pip looks for the following device for the CD ROM writer.
	    IMS     CDD521/10
       Pip looks for one of the following devices for the CD ROM reader.  The  Philips	will  not
       read cdda format and the NEC does not work well with pip.  The Toshiba does not accurately
       seek on cdda media.  We recommend the Plextor.  The first column is the device  name  that
       should be given in the interactive commands.

	    nec  NEC	 CD-ROM DRIVE:8411.0

       The following commands are recognized.

       help   Print a one line description of each command.

       load device track format disktrack
	      A  track	is copied from the device to the designated track on the disk.	The track
	      is a number or *, designating all tracks.  If the copy completes normally, the  old
	      data on that disk track is lost.	format is either cdda or cdrom.

       verif device track format disktrack
	      This  is	the  same as load except that the data is not copied, but compared to the
	      data on the disk.  The compare allows a slip of multiples of four  bytes	as  might
	      occur copying an audio CD with imprecise seek.

       store track file
	      The  disk  track is written to a regular Plan 9 file.  The track may be a number or
	      *.  If the track is *, then the string file is prefixed to  the  track  number  for
	      every track.

       toc [device]
	      Will  print  the table of contents of the specified device.  If no device is given,
	      then the track table of contents of the disk is given.

	      All tracks on the disk are deleted.

       remove track
	      The specified track on the disk is deleted.

       sum track
	      The specified disk track is read and checksummed.

       publish track
	      The specified disk track is copied to the next track on the Philips CD writer.  The
	      format  of  the  data  is  not  specified  until	the table of contents is written.
	      Although it is not required, it is usual that all tracks are the same format.

       fixate format
	      Issue a fixate command to the Philips CD writer.	Format is either cdda  or  cdrom.
	      This makes the table of contents permanent.

       session format
	      Issue  a	session  command  to  the  Philips CD writer.  This is the same as fixate
	      except that a second session is opened and more data may be put on  the  CD.   Most
	      readers can only see the table of contents from the first session.

       9660 proto track
	      A  filesystem  description is read from the proto file in mkfs(8) format.  The file
	      system is converted to ISO 9660 format and written on the specified disk track.

       The first line of the proto file for the 9660 command is parsed for options.  The  follow-
       ing options are recognized.

       -c     Convert  all  file names in the file system so that they conform to 9660 standards.
	      (Roughly this is eight or fewer single case alphanumerics followed by  an  optional
	      period  and three or fewer single case alphanumerics.)  File names that conform are
	      converted from lower case letters in the input file system to  upper  case  in  the
	      output  file system.  Names that do not conform are renamed to Fnumber and directo-
	      ries are renamed Dnumber.  A file named _CONFORM.MAP is created in the root of  the
	      output file system with old-name new-name pairs of all converted files.

       -e     Add  a system-use field to every directory record that contains the name, uid, gid,
	      and mode of the file.  With or without this extension, directory records conform to
	      the 9660 standard and should be able to be read on other systems.

       -a file
	      Places  the named file in the abstract field of the primary volume descriptor.  The
	      file must be in the root directory.

       -b file
	      Places the named file in the bibliographic field of the primary volume  descriptor.
	      The file must be in the root directory.

       -n file
	      Places the named file in the copyright field of the primary volume descriptor.  The
	      file must be in the root directory.

       -s dir Prefix the directory name dir to the names of files in the proto file.   This  per-
	      mits  a  file  tree  to  be assembled cleanly under a special directory, to be then
	      copied into the new file system at the root.

       -v     Print each file name as it is copied.

       All dates in the output file system are set to the date the  command  was  executed.   The
       volume  identifier  field of the primary volume descriptor is set to the last component of
       the proto file name.  The system identifier field of the primary volume descriptor is  set
       to  PLAN  9,  and  should  be  keyed to the interpretation of the system-use fields of the
       directory records.

       To cut your own audio CD with your favorite CDs:

       load plex 5 cdda 1  # read track 5 from an audio CD
       load plex 2 cdda 2  # read track 2 from an audio CD
       load ... 	   # etc.
       publish *	   # write all tracks to Philips CD writer
       fixate cdda	   # write table of contents

       To cut your own 9660 CD-ROM:

       mount /srv/bootes /n/bootes   # make a clean, bind-free tree
       9660 mkfs 4	   # make a 9660 image from a mkfs specification
			   # for the Plan 9 distribution
			   # the first line of mkfs is
			   # -s /n/bootes -c -e -n notice
       publish 4	   # write 9660 image to Philips CD writer
       fixate cdrom	   # write table of contents



       The program only knows about a few devices.  The tables and device code must  be  extended
       to  be  more comprehensive.  The industry has not adopted a standard way to read and write
