3/19/08: Update: I have verified that this compiles with libewf-20070512.

3/21/08: Bug Fix: Deleted Ext/FFS directories were not being recursed
into.  This case was rare (because typically the metadata  are

new FS_FLAG_META_COMP and FS_FLAG_DATA_COMP flags to show if a file
and data are using file system-level compression (NTFS only).

10/18/06: Bug fix: in fs_data_put_run, added a check to see
if the head was null before looking up.  An extra error message
was being created for nothing.

unallocated entries were found that had an MFT entry address of 0.
Reported by Robert-Jan Mora.

8/16/06: Update: Changed a lot of the header files and reduced them so
that it is easier to use the library and only one header file needs to

changes, not many external changes.  error() function no longer used
and instead tsk_err variables and function are used.  This makes the
library more powerful.

4/5/06: Update: The byte offset for a volume is now passed to the mm_
and fs_ functions instead of img_open.  This allows img_info to be used
for multiple volumes at the same time. This required some mm_ changes.

and ExtX.

9/2/05: Update: Upgraded file to version 4.15.

9/2/05: Update: The dent_walk code of all file systems does not
abort if a sub-directory is encountered with an error.  If it is the
top directory explicitly called, then it still gives an error.

9/2/05: Bug Fix: MD5 and SHA-1 values were incorrect under AMD64 
systems because the incorrect variable sizes were being used.
(reported by: Regis Friend Cassidy. BUG: 1280966)

9/2/05: Update: Changed all licenses in TSK to Common Public License
(except those that were already IBM Public License).

9/15/05: Bug Fix: The Unicode names would not be displayed if the FAT
short name entry was using code pages.  The ASCII name check was removed,
which may lead to more false positives during inode_walk.

10/05/05: Update: improved the sector size check when the FAT boot
sector is read (check for specific values besides just mod 512).

10/12/05: Update: The ASCII name check was added back into FAT, but
the check no longer looks for values over 0x80.

10/12/05: Update: The inode_walk function in FAT skips clusters
that are allocated to files.  This makes it much faster, but it
will now not find unallocated directory entries in the slack space
of allocated files.

10/13/05: Update: sorter updated to handle unicode in HTML output.

---------------- VERSION 2.02 --------------
4/27/05: Bug Fix: the sizes of 'id' were not consistent in the
front-end and library functions for icat and ffind.  Reported by
John Ward.

5/16/05: Bug Fix: fls could segfault in FAT if short name did not
exist.  There was also a bug where the long file name variable
(fatfs->lfn_len) was not reset after processing a directory and the
next entry could incorrectly get the long name.  Reported by Jaime
Chang.  BUG: 1203673.

5/18/05: Update: Updated makedefs to support Darwin 8 (OS X Tiger)

5/23/05: Bug Fix: ntfs_dent_walk would not always stop when WALK_STOP
was returned.  This caused some issues with previous versions of ifind.
This was fixed.

5/24/05: Bug Fix: Would not compile under Suse because it had header

Chang).

6/13/05: Update: Compiled with g++ to get better warning messages.
Fixed many signed versus unsigned comparisons, -1 assignments to
unsigned vars, and some other minor internal issues.

6/13/05: Bug Fix: if UFS or FFS found a valid dentry in unallocated
space, it could have a documented length that is larger than the
remaining unallocated space.  This would cause an allocated name
to be skipped.  BUG: 1210204  Reported by Christopher Betz.

6/13/05: Update: Improved design of all dent code so that there are no 
more global variables.  

6/13/05: Update: Improved design of FAT dent code so that FATFS_INFO
does not keep track of long file name information.

6/13/05: Bug Fix: If a cluster in a directory started with a strange
dentry, then FAT inode_walk would skip it.  The fixis to make sure
that all directory sectors are processed.  (BUG: 1203669).  Reported
by Jaime Chang.

6/14/05: Update: Changed design of FS_INODE so that it contains the
inode address and the inode_walk action was changed to remove inum
as an argument.

6/15/05: Update: Added 'ils -o' back in as 'ils -O' to list open
and deleted files.

6/15/05: Update: Added '-m' flag to mactime so that it prints the month
as a number instead of its name.

7/2/05: Bug Fix: If an NTFS file did not have a $DATA or $IDX_*
attribute, then fls would not print it.  The file had no content, but
the name should be shown.  (BUG: 1231515) (Reported by Fuerst)


---------------- VERSION 2.01 --------------
3/24/05: Bug Fix: ffind would fail if the directory had two
non-printable chars.  The handling of non-printable chars was changed
to replace with '^.'.  (BUG: 1170310) (reported by Brian Baskin)

3/24/05: Bug Fix: icat would not print the output to stdout when split
images were used.  There was a bug in the image closing process of
icat.  (BUG: 1170309) (reported by Brian Baskin)

3/24/05: Update: Changed the header files in fstools to make fs_lib.h
more self contained.

4/1/05: Bug Fix: Imgtools byte offset with many leading 0s could
cause issues.  (BUG: 1174977)

4/1/05: Update: Removed test check in mmtools/dos.c for value cluster
size because to many partition tables have that as a valid field.
Now it checks only OEM name.

4/8/05: Update: Updated usage of 'strtoul' to 'strtoull' for blocks
and inodes.

---------------- VERSION 2.00 --------------
1/6/05: Update: Added '-b' flag to 'mmls' so that sizes can be
printed in bytes.  Suggested and a patch proposed by Matt Kucenski

1/6/05: Update: Define DADDR_T, INUM_T, OFF_T, PNUM_T as a static
size and use those to store values in data structures.   Updated
print statements as well.

1/6/05: Update: FAT now supports larger images becuase the inode
address space is 64-bits.

1/6/05: Moved guess and get functions to misc from mmtools and
fstools.

1/7/05: Update: Added imgtools with support for "raw" and "split"
layers.  All fstools have been updated.

1/7/05: Update: removed dtime from ils output

1/9/05: Update: FAT code reads in clusters instead of sectors to
be faster (suggested by David Collett)

1/9/05: Update: mmtools uses imgtools for split images etc.

1/10/05: Update: Removed usage of global variables when using
file_walk internally.

1/10/05: Update: mmls BSD will use the next sector automatically
if the wrong is given instead of giving an error.

1/10/05: Update: Updated file to version 4.12

1/11/05: Update: Added autodetect to file system tools.

1/11/05: Update: Changed names to specify file system type (not

1/11/05: Update: Added autodetect to mmls

1/17/05: Update: Added the 'mmstat' tool that gives the type of
volume system.

1/17/05: Update: Now using CVS for local version control - added
date stamps to all files.

2/20/05: Bug Fix: ils / istat would go into an infinte loop if the
attribute list had an entry with a length of 0.  Reported by Angus
Marshall (BUG: 1144846)

3/2/05: Update: non-printable letters in ExtX/UFS file names are
now replaced by a '.'

3/2/05: Update: Made file system tools more library friendly by 
making stubs for each application.

3/4/05: Update: Redesigned the diskstat tool and created the
disksreset tool to remove the HPA temporarily.

3/4/05: Update: Added imgstat tool that displays image format
details

3/7/05: Bug Fix: In fsstat on ExtX, the final group would have an
incorrect _percentage_ of free blocks value (although the actual
number was correct).  Reported by Knut Eckstein.  (BUG: 1158620)

3/11/05: Update: Renamed diskstat, disksreset, sstrings, and imgstat to
disk_stat, disk_sreset, srch_strings, and img_stat to make the names more
clear. 

3/13/05: Bug Fix: The verbose output for fatfs_file_walk had an
incorrect sector address.  Reported by Rudolph Pereira.

3/13/05: Bug Fix: The beta version had compiling problems on FreeBSD
because of a naming clash with the new 'fls' functions. (reported
by secman)



---------------- VERSION 1.74 --------------
11/18/04: Bug Fix: FreeBSD 5 would produce incorrect 'icat' output for
Ext2/3 & UFS1 images because it used a 64-bit on-disk address. 
reported by neutrino neutrino.  (BUG: 1068771)

11/30/04: Bug Fix: The makefile in disktools would generate an error
on some systems (Cygwin) because of an extra entry.  Reported by

---------------- VERSION 1.73 --------------
09/09/04: Update: Added journal support for EXT3FS and added jls
and jcat tools.

09/13/04: Updated: Added the major and minor device numbers to
EXTxFS istat.

09/13/04: Update: Added EXTxFS orphan code to 'fsstat'

09/24/04: Update: Fixed incorrect usage of 'ptr' and "" in action

  future.  Reported by Pete Winkler.

09/25/04: Update: Added UFS flags to fsstat

09/26/04: Update: All fragments are printed for indirect block pointer
  addresses in UFS istat.

09/29/04: Update: Print extended UFS2 attributes in 'istat'

10/07/04: Bug Fix: Changed usage of (int) to (uintptr_t) for pointer
arithmetic. Caused issues with Debian Sarge. (BUG: 1049352) - turned out
to be from changes made to package version so that it would compile in
64-bit system (BUG: 928278).

10/11/04: Update: Added diskstat to check for HPA on linux systems.

10/13/04: Update: Added root directory location to FAT32 fsstat output

10/17/04: Bug Fix: EXTxFS superblock location would not be printed
for images in fsstat that did not have sparse superblok (which is
rare)  (BUG: 1049355)

10/17/04: Update: Added sigfind tool to find binary signatures.

10/27/04: Bug Fix: NTFS is_clust_alloc returned an error when loading
  $MFT that had attribute list entry.  Now I assume that clusters 
  referred to by the $MFT are allocated until the $MFT is loaded.
  (BUG: 1055862).

10/28/04: Bug Fix: Check to see if an attribute with the same name
  exists instead of relying on id only. (ntfs_proc_attrseq) Affects
  the processing of attribute lists.  Reported by Szakacsits Szabolcs,
  Matt Kucenski, & Gene Meltser (BUG: 1055862)

10/28/04: Update: Removed usage of mylseek in fstools for all systems
  (Bug: 928278)


---------------- VERSION 1.72 --------------
07/31/04: Update: Added flag to mft_lookup so that ifind can run in noabort
mode and it will not stop when it finds an invalid magic value.

08/01/04: Update: Removed previous change and removed MAGIC check
entirely.  XP doesn't even care if the Magic is corrupt, so neither
does TSK.  The update sequence check should find an invalid MFT
entry.

08/01/04: Update: Added error message to 'ifind' if none of the search
options are given.

08/05/04: Bug Fix: Fixed g_curdirptr recursive error by clearing the value
when dent_walk had to abort because a deleted directory could not be recovered.
(BUG:  1004329)  Reported by epsilon@yahoo.com

08/16/04: Update: Added a sanity check to fatfs.c fat2unixtime to check
if the year is > 137 (which is the overflow date for the 32-bit UNIX time).

08/16/04: Update: Added first version of sstrings from binutils-2.15

08/20/04: Bug Fix: Fixed a bug where the group number for block 0 of an 
EXT2FS file system would report -1. 'dstat' no longer displays value when it
is not part of a block group. (BUG: 1013227)

8/24/04: Update: If an attribute list entry is found with an invalid MFT
entry address, then it is ignored instead of an error being generated and
exiting.

8/26/04: Update: Changed internal design of NTFS to make is_clust_alloc

8/26/04: Update: If an attribute list entry is found with an invalid MFT
entry address AND the entry is unallocated, then no error message is 
printed, it is just ignored or logged in verbose mode.

8/29/04: Update: Added support for 32-bit GID and UID in EXTxFS

8/30/04: Bug Fix: ntfs_dent_walk was adding 24 extra bytes to the
size of the index record for the final record processing (calc of
list_len) (BUG: 1019321) (reported and debugging help from Matt
Kucenski).

8/30/04: Bug Fix: fs_data_lookup was using an id of 0 as a wild
card, but 0 is a legit id value and this could cause confusion.  To
solve this, a new FS_FLAG_FILE_NOID flag was added and a new
fs_data_lookup_noid function that will not use the id to lookup
values.  (BUG: 1019690) (reported and debugging help from Matt
Kucenski)

8/30/04: Update: modified fs_data_lookup_noid to return unamed data
attribute if that type is requested (instead of just relying on id
value in attributes)

8/31/04: Update: Updated file to v4.10, which seems to fix the
CYGWIN compile problem.

9/1/04: Update: Added more DOS partition types to mmls (submitted by
Matt Kucenski)

9/2/04: Update: Added EXT3FS extended attributes and Posix ACL to istat
output.

9/2/04: Update: Added free inode and block counts per group to fsstat for
EXT2FS.

9/7/04: Bug Fix: FreeBSD compile error for PRIx printf stuff in mmtools/gpt.c


---------------- VERSION 1.71 --------------
06/05/04: Update: Added sanity checks in fat to unix time conversion so that
invalid times are set to 0.

06/08/04: Bug Fix: Added a type cast when size is assigned in FAT 
and removed the assignment to a 32-bit signed variable (which was no
longer needed).  (Bug: 966839)

06/09/04: Bug Fix: Added a type cast to the 'getuX' macros because some
compilers were assuming it was signed (Bug: 966839).  

06/11/04: Update: Changed NTFS magic check to use the aa55 at the
end and fixed the name of the original "magic" value to oemname.
The oemname is now printed in fsstat.

06/12/04: Bug Fix: The NTFS serial number was being printed with
bytes in the wrong order in the fsstat output. (BUG: 972207)

06/12/04: Update: The begin offset value in index header for NTFS 
was 16-bits instead of 32-bits.

06/22/04: Update: Created a library for the MD5 and SHA1 functions so
that it can be incorporated into other tools.  Also renamed some of the
indexing tools that hfind uses.

06/23/04: Update: Changed output of 'istat' for NTFS images.  Added more
data from $STANDARD_INFORMATION.  

07/13/04: Update: Changed output of 'istat' for NTFS images again.  Moved
more data to the $FILE_NAME section and added new data.

07/13/04: Update: Changed code for processing NTFS runs and no
longer check for the offset to be 0 in ntfs_make_data_run().  This
could have prevented some sparse files from being processed.

07/13/04: Update: Added flags for compressed and encrypted NTFS
files.  They are not decrypted or uncompressed yet, just identified.
They cannot be displayed from 'icat', but the known layout is given
in 'istat'.

07/18/04: Bug Fix: Sometimes, 'icat' would report an error about an
existing FILLER entry in an NTFS attribute.  This was traced to
instances when it was run on a non-base file record.  There is now
a check for that to not show the error. (BUG: 993459)

07/19/04: Bug Fix: A run of -1 may exist for sparse files in non-NT
versions of NTFS.  Changed check for this.  reported by Matthew
Kucenski.  (BUG: 994024).

07/24/04: Bug Fix: NTFS attribute names were missing (rarely) on
some files because the code assumed they would always be at offset
64 for non-res attributes (Bug: 996981).

07/24/04: Update: Made listing of unallcoated NTFS file names less
strict.  There was a check for file name length versus stream length.

07/24/04: Update: Added $OBJECT_ID output to 'istat'

07/24/04: Update: Fixed ntfs.c compile warning about constant too
large in time conversion code.

07/25/04: Update: Added attribute list contents to NTFS 'istat' output

07/25/04: Bug Fix: Not all slack space was being shown with 'dls -s'.
It was documented that this occurs, but it is not what would be
expected.  (BUG: 997800).

07/25/04: Update: Changed output format of 'dls -s' so that it sends
zeros where the file content was.  Therefore the output is now a
multiple of the data unit size.  Also removed limitation to FAT &
NTFS.

07/25/04: Update: 'dcalc' now has the '-s' option calculate the 
original location of data from a slack space image (dls -s).  
(from Chris Betz).  

07/26/04: Update: Created the fs_os.h file and adjusted some of the 
header files for the PRI macros (C99).  Created defines for OSes that do
not have the macros already defined.  

07/26/04: Non-release bug fix: Fixed file record size bug introduced with
recent changes.

07/27/04: Update: Added GPT support to mmls.

07/29/04: Update: Added '-p' flag to 'ifind' to find deleted NTFS files 
that point to the given parent directory.  Added '-l and -z' as well.


---------------- VERSION 1.70 --------------
04/21/04: Update: Changed attribute and mode for FAT 'istat' so
that actual FAT attributes are used instead of UNIX translation.

04/21/04: Update: The FAT 'istat' output better handles Long FIle
Name entry

04/21/04: Update: The FAT 'istat' output better handles Volume Label
entry

04/21/04: Update: Allowed the FAT volume label entry to be displayed
with 'ils'

04/21/04: Update: Allowed the FAT volume label entry to be displayed
with 'fls'

04/24/04: Update: 'dstat' on a FAT cluster now shows the cluster
address in addition to the sector address.

04/24/04: Update: Added the cluster range to the FAT 'fsstat' output

05/01/04: Update: Improved the FAT version autodetect code.  

05/02/04: Update: Removed 'H' flag from 'icat'.

05/02/04: Update: Changed all of the FS_FLAG_XXX variables in the
  file system tools to constants that are specific to the usage
  (NAME, DATA, META, FILE).  

05/03/04: Update: fatfs_inode_walk now goes by sectors instead of clusters
  to get more dentries from slack space.

05/03/04: Bug Fix: The allocation status of FAT dentires was set only by
  the flag and not the allocation status of the cluster it is located in.
  (BUG: 947112)

05/03/04: Update: Improved comments and variable names in FAT code

05/03/04: Update: Added '-r' flag to 'icat' for deleted file recovery

05/03/04: Update: Added RECOVERY flag to file_walk for deleted file
  recovery

05/03/04: Update: Added FAT file recovery.  

05/03/04: Update: Removed '-H' flag from 'icat'.  Default is to 
  display holes.
  
05/03/04: Update: 'fls -r' will recurse down deleted directories in FAT

05/03/04: Update: 'fsstat' reports FAT clusters that are marked as BAD

05/03/04: Update: 'istat' for FAT now shows recovery clusters for 
  deleted files.

05/04/04: Update:  Added output to 'fsstat' for FAT file systems by adding
  a list of BAD sectors and improving the amount of layout information.  I
  also changed some of the internal variables. 

05/08/04: Update: Removed addr_bsize from FS_INFO, moved block_frags 
  to FFS_INFO, modified dcat output only data unit size.

05/20/04: Update: Added RECOVERY flag to 'ifind' so that it can find the
  data units that are allocated to deleted files

05/20/04: Update: Added icat recovery options to 'sorter'.

05/20/04: Update: Improved the naming convention in sorter for the 'ils' 
  dead files.

05/21/04: Update: Added outlook to sorter rules (from David Berger)

05/27/04: Bug Fix: Added <linux/unistd.h> to mylseek.c so that it compiles
with Fedora Core 2 (Patch by Angus Marshall) (BUG: 961908).

05/27/04: Update: Changed the letter with 'fls -l' for FIFO to 'p' 
instead of 'f' (reported by Dave Henkewick).

05/28/04: Update: Added '-u' flag to 'dcat' so that the data unit size
can be specified for raw, swap, and dls image types.

05/28/04: Update: Changed the size  argument  of 'dcat' to be number of
data units instead of size in bytes (suggestion by Harald Katzer).


---------------- VERSION 1.69 --------------
03/06/04: Update: Fixed some memory leaks in ext2fs_close.  reported
  by Paul Bakker.
03/10/04: Bug Fix: If the '-s' flag was used with 'icat' on a EXT2FS
  or FFS file system, then a large amount of extra data came out.
  Reported by epsion.  (BUG: 913874)
03/10/04: Bug Fix: One of the verbose outputs in ext2fs.c was being sent
  to STDOUT instead of logfp. (BUG: 913875)
04/14/04: Update: Added more data to fsstat output of FAT file system.
04/15/04: Bug Fix:  The last sector of a FAT file system may not
  be analyzed.  (BUG: 935976)
04/16/04: Update: Added full support for swap and raw by making the
 standard files and functions for them instead of the hack in dcat.
 Suggested by (and initial patch by) Paul Baker.
04/18/04: Update: Changed error messages in EXT2/3FS  code to be extXfs.
04/18/04: Update: Updaged to version 4.09 of 'file'.  This will
  help fix some of the problems people have had compiling it under
  OS X 10.3.
04/18/04: Update: Added compiling support for SFU 3.5 (Microsoft).  Patches
  from an anonymous person.


---------------- VERSION 1.68 --------------
01/20/04: Bug Fix: FAT times were an hour too fast during daylight savings.
  Now use mktime() instead of manual calculation.  Reported by Randall 
  Shane. (BUG: 880606)
02/01/04: Update: 'hfind -i' now reports the header entry as an invalid
  entry.  The first header row was ignored.
02/20/04: Bug Fix: indirect block pointer blocks would not be identified by
 the ifind tool.  Reported by Knut Eckstein (BUG: 902709)
03/01/04: Update: Added fs->seek_pos check to fs_read_random.

---------------- VERSION 1.67 --------------
11/15/03: Bug Fix: Added support for OS X 10.3 to src/makedefs. (BUG: 843029)
11/16/03: Bug Fix: Mac partition tables could generate an error if there were
  VOID-type partitions.   (BUG: 843366)
11/21/03: Update: Changed NOABORT messages to verbose messages, so invalid
  data is not printed during 'ifind' searches.
11/30/03: Bug Fix: icat would not hide the 'holes' if '-h' was given because
  the _UNALLOC flag was always being passed to file_walk.  (reported by
  Knut Eckstein).  (BUG: 851873)
11/30/03: Bug Fix: NTFS data_walk was not using _ALLOC and _UNALLOC flags 
  and other code that called it was not either.  (BUG: 851895)
11/30/03: Bug Fix:  Not all needed commands were using _UNALLOC when they
  called file_walk (although for most cases it did not matter because
  sparse files would not be found in a directory for example). (Bug: 851897)  
12/09/03: Bug Fix: FFS and EXT2FS code was using OFF_T type instead of
  size_t for the size of the file. This could result in a file > 2GB
  as being a negative size on some systems (BUG: 856957). 
12/26/03: Bug Fix: ffind would crash for root directory of FAT image.
  Added NULL check and added a NULL name to fake root directory entry.
  (BUG: 871219)
01/05/04: Bug Fix: The clustcnt value for FAT was incorrectly calculated
  and was too large for FAT12 and FAT16 by 32 sectors.  This could produce
  extra entries in the 'fsstat' output when the FAT is dumped.  
  (BUG: 871220)
01/05/04: Bug Fix: ils, fls, and istat were not printing the full size
  of files that are > 2GB.  (reported by Knut Eckstein) (BUG: 871457) 
01/05/04: Bug Fix: The EXT2FS and EXT3FS code was not using the
  i_dir_acl value as the upper 32-bits of regular files that are
  > 2GB (BUG:  871458)
01/06/04: Mitigation: An error was reported where sorter would error
  that icat was being passed a '-1' argument.  I can't find how that would
  happen, so I added quotes to all arguments so that the next time it 
  occurs, the error is more useful (BUG: 845840).
01/06/04: Update: Incorporated patch from Charles Seeger so that 'cc'
  can be used and compile time warnings are fixed with Sun 'cc'.  
01/06/04: Update: Upgraded file from v3.41 to v4.07


---------------- VERSION 1.66 --------------
09/02/03: Bug Fix: Would not compile under OpenBSD 3 because fs_tools.h
  & mm_tools was missing a defined statement (reported by Randy - m0th_man)
NOTE: Bugs now will have an entry into the Source Forge bug tracking
  sytem.  
10/13/03: Bug Fix: buffer was not being cleared between uses and length
 incorrectly set in NTFS resulted in false deleted file names being shown
 when the '-r' flag was given.  The extra entries were from the previous
 directory.  (BUG: 823057)
10/13/03: Bug Fix: The results of 'sorter' varied depending on the version
  of Perl and the system.   If the file output matched more than one,
  sorter could not gaurantee which would match.  Therefore, results were
  different for some files and some machines.  'sorter' now enforces the
  ordering based on the order they are in the configuration file.  The
  entries at the end of the file have priority over the first entries
  (generic rules to specific rules).  (BUG: 823057)
10/14/03: Update: 'mmls' prints 'MS LVM' with partition type 0x42 now.
10/25/03: Bug Fix: NTFS could have a null pointer crash if the image
  was very corrupt and $Data was not found for the MFT.  
11/10/03: Bug Fix: NTFS 'ffind' would only report the file name and not
  the attribute  name because the type and id were ignored.  ffind and
  ntfs_dent were updated - found during NTFS keyword search test.
  (Bug: 831579()
11/12/03: Update: added support for Solaris x86 partition tables to 'mmls'
11/12/03: Update: Modified the sparc data structure to add the correct 
  location of the 'sanity' magic value.
11/15/03: Update: Added '-s' flag to 'icat' so that slack space is also
  displayed.

---------------- VERSION 1.65 --------------
08/03/03: Bug Fix: 'sorter' now checks for inode values that are too
  small to avoid 'icat' errors about invalid inode values.  
08/19/03: Update: 'raw' is now a valid type for 'dcat'.
08/21/03: Update: mactime and sorter look for perl5.6.0 first.
08/21/03: Update: Removed NSRL support from 'sorter' until a better
 wany to identify the known good and known bad files is found
08/21/03: Bug Fix: The file path replaces < and > with HTML 
  encoding for HTML output (ils names were not being shown)
08/25/03: Update: Added 'nsrl.txt' describing why the NSRL functionality
  was removed.
08/27/03: Update: Improved code in 'mactime' to reduce warnings when
  '-w' is used with Perl ('exists' checks on arrays).
08/27/03: Update: Improved code in 'sorter' to reduce warnings when
  '-w' is used with Perl (inode_int for NTFS).

---------------- VERSION 1.64 --------------
08/01/03: Docs Fix: The Sun VTOC was documented as Virtual TOC and it
  should be Volume TOC (Jake @ UMASS).
08/02/03: Bug Fix: Some compilers complained about verbose logging

  was not correct (reported by Stephane Denis).  
11/24/02: Bug Fix: The -v argument was not allowed on istat or fls (Michael
  Stone)
11/24/02: Bug Fix: When doing an 'ifind' on a UNIX fs, it could abort if it
  looked at an unallocated inode with invalid indirect block pointers.
  This was fixed by adding a "NOABORT" flag to the walk code and adding
  error checks in the file system code instead of relying on the fs_io
  code.  (suggested by Micael Stone)
11/26/02: Update: ifind has a '-n' argument that allows one to specify a
  file name it and it searches to find the meta data structure for it
  (suggested by William Salusky).
11/26/02: Update: Now that there is a '-n' flag with 'ifind', the '-d'
  flag was added to specify the data unit address.  The old syntax of
  giving the data_unit at the end is no longer supported.  
11/27/02: Update: Added sanity checks on meta data and data unit addresses
  earlier in the code.
12/12/02: Update: Added additional debug statements to NTFS code

  properly NULL terminated and some extra chars were appended in 'fls'
  (later reported by Thorsten Zachmann)

  file systems if the end fragments were allocated to a different file than
  the first ones were.
01/07/03: Update: Renamed the src/mactime directory to src/timeline.
01/07/03: Update: Updated README and man pages for hfind and sorter
01/12/03: Bug Fix: ntfs_mft_lookup was casting a 64-bit value to a 32-bit
  variable.  This caused MFT Magic errors.  Reported and debugged by 
  Keven Murphy

  done using upd_off, which will allow for NTFS to move the structure in
  the future.
09/26/02: Update: Added create time for NTFS / STANDARD_INFO to 
  istat output.
09/26/02: Update: Changed the method that the NTFS time is converted
  to UNIX time.  Should be more efficient.
10/09/02: Update: dcat error changed.
10/02/02: Update: Includes a Beta version of 'sorter'


---------------- VERSION 1.51 --------------
09/10/02: Bug Fix: Fixed a design bug that would not allow attribute 
  lists in $MFT.  This bug would generate an error that complained about
  an invalid MFT entry in attribute list.  
09/10/02: Update: The size of files and directories is now calculated
  after each time proc_attrseq() is called so that it is more up to date
  when dealing with attribute lists.  The size has the sizes of all
  $Data, $IDX_ROOT, and $IDX_ALLOC streams. 
09/10/02: Update: The maxinum number of MFT entries is now calculated
  each time an MFT entry is processed while loading the MFT.  This 
  allows us to reflect what the maximum possible MFT entry is at that
  given point based on how many attribute lists have been processed.
09/10/02: Update: Added file version 3.39 to distro (bigger magic files) 
  (Salusky)
09/10/02: Bug Fix: fs_data was wasting memory when it was allocated
09/10/02: Update: added a fs_data_alloc() function
09/12/02: Bug Fix: Do not give an error if an attribute list of an
  unallocated file points to an MFT that no longer claims it is a 
  member of the list.
09/12/02: Update: No longer need version to remove update sequence
  values from on-disk buffers
09/19/02: Bug Fix: fixed memory leak in ntfs_load_ver() 
09/19/02: Bug Fix: Update sequence errors were displayed because of a
  bug that occurred when an MFT entry crossed a run in $MFT.  Only occurred
  with 512-byte clusters and an odd number of clusters in a run.
09/19/02: Update: New argument to ils, istat, and fls that allows user to
  specify a time skew in seconds of the compromised system.  Originated
  from discussion at DFRWS II.  
09/19/02: Update: Added '-h' argument to mactime to display header info 

---------------- VERSION 1.50 --------------

05/19/02: Changed icat so that the default attribute type is set in the
  file_walk function
05/20/02: ils and dls now use boundary inode & block values if too large
  or small are given
05/21/02: istat now displays all NTFS times
05/21/02: Created functions to just display date and time
