Recover v1.0 ©1993 Diemar Eilert
 -------------------------------------------------------------------------------

 A  program to recover text buffers after your system has chrashed. Recover will
 scan  all  available  memory  locations (the free memory pool as well as memory
 allocated  by  other task), looking for lost buffers. Since freed memory is not
 protected by the OS, lost buffers may become trashed. Recover will still try to
 restore  trashed  buffers  but  they  may contain garbage lines. You'll have to
 verify  that  restored  buffers  are  intact before you copy them over your old
 files.  Recover will try to figure out how many lines are corrupt to give you a
 rough  idea of wether additional work is required. Be warned: these figures are
 not  exact  since  it's  hard  to determine wether a line is corrupt or not. To
 increase  your  chances,  run  this program as soon as possible. Interrupt your
 startup  sequence  (type CTRL-D) and run recover IMMEDIATELY. Don't run Recover
 if  your  system is badly damaged (task held requester): Instead, reboot before
 attempting  to  recover  lost  buffers.  Recover  disables  multitasking  while
 scanning memory to prevent other tasks from allocating memory - this means that
 your  mouse  pointer  freezes  temporarily.  Recover should be run from a shell
 window. The following arguments are supported:

               RECOVER DRIVE/K,ALL/S,TEST/S,MAXLEN/N,MAXLINES/N

 DRIVE
 -----

 Drive  where  to  write restored files (e.g. df0:). 

 *******************************************************************************
 * Don't  use  a ram disk (might overwrite the text to recover) or a hard disk *
 * (program might fail while writing since it has to do some dangerous stuff) !*
 *******************************************************************************

 ALL
 ---

 Recover file even if it appears to be unchanged (Recover defaults to ignoring a
 text if it has never been modified).

 TEST
 ----

 Just scan memory for text buffers to recover but don't write to a disk. Recover
 tries  to figure out how many lines can be restored respectively are corrupt. A
 line  is considered corrupt if it containes ASCII-Codes below 32 or from 128 to
 160.  Nevertheless,  even  corrupt  lines  are restored since parts of them may
 still be usable.

 
 MAXLEN
 ------

 Maximum  line  lenght to be considered valid. If Recover happens to encounter a
 longer  line while scanning memory it will refuse to restore the line (might be
 corrupt). Defaults to 255.

 MAXLINES
 --------

 Maximum  number  of  lines (per text) to restore. Recover will stop recovery as
 soon  as  a  text  exeeds this limit (text might be corrupt). Defaults to 10000
 lines.
