+   -h, --help
+         Print a usage message and exit.
+   -V, --version
+         Print version number and exit.
+   -r, --report
+         Report mode. Print differences.
+   -v --verbose
+         Verbose mode. Print differences information and list of objects.
+   -vN --verbose=N
+         Verbose mode with level. Print differences and list of objects.
+         Level of detail depends on value of N:
+          0 : Identical to '-v' or '--verbose'.
+          1 : All level 0 information plus one-line attribute
+              status summary.
+          2 : All level 1 information plus extended attribute
+              status report.
+   -q, --quiet
+         Quiet mode. Do not produce output.
+   --follow-symlinks
+         Follow symbolic links (soft links and external links and compare the)
+         links' target objects.
+         If symbolic link(s) with the same name exist in the files being
+         compared, then determine whether the target of each link is an existing
+         object (dataset, group, or named datatype) or the link is a dangling
+         link (a soft or external link pointing to a target object that does
+         not yet exist).
+         - If both symbolic links are dangling links, they are treated as being
+           the same; by default, h5diff returns an exit code of 0.
+           If, however, --no-dangling-links is used with --follow-symlinks,
+           this situation is treated as an error and h5diff returns an
+           exit code of 2.
+         - If only one of the two links is a dangling link,they are treated as
+           being different and h5diff returns an exit code of 1.
+           If, however, --no-dangling-links is used with --follow-symlinks,
+           this situation is treated as an error and h5diff returns an
+           exit code of 2.
+         - If both symbolic links point to existing objects, h5diff compares the
+           two objects.
+         If any symbolic link specified in the call to h5diff does not exist,
+         h5diff treats it as an error and returns an exit code of 2.
+   --no-dangling-links
+         Must be used with --follow-symlinks option; otherwise, h5diff shows
+         error message and returns an exit code of 2.
+         Check for any symbolic links (soft links or external links) that do not
+         resolve to an existing object (dataset, group, or named datatype).
+         If any dangling link is found, this situation is treated as an error
+         and h5diff returns an exit code of 2.
+   -c, --compare
+         List objects that are not comparable
+   -N, --nan
+         Avoid NaNs detection
+   -n C, --count=C
+         Print differences up to C. C must be a positive integer.
+   -d D, --delta=D
+         Print difference if (|a-b| > D). D must be a positive number.
+         Can not use with '-p' or '--use-system-epsilon'.
+   -p R, --relative=R
+         Print difference if (|(a-b)/b| > R). R must be a positive number.
+         Can not use with '-d' or '--use-system-epsilon'.
+   --use-system-epsilon
+         Print difference if (|a-b| > EPSILON), EPSILON is system defined value.
+         If the system epsilon is not defined,one of the following predefined
+         values will be used:
+           FLT_EPSILON = 1.19209E-07 for floating-point type
+           DBL_EPSILON = 2.22045E-16 for double precision type
+         Can not use with '-p' or '-d'.
+   --exclude-path "path" 
+         Exclude the specified path to an object when comparing files or groups.
+         If a group is excluded, all member objects will also be excluded.
+         The specified path is excluded wherever it occurs.
+         This flexibility enables the same option to exclude either objects that
+         exist only in one file or common objects that are known to differ.
+
+         When comparing files, "path" is the absolute path to the excluded;
+         object; when comparing groups, "path" is similar to the relative
+         path from the group to the excluded object. This "path" can be
+         taken from the first section of the output of the --verbose option.
+         For example, if you are comparing the group /groupA in two files and
+         you want to exclude /groupA/groupB/groupC in both files, the exclude
+         option would read as follows:
+           --exclude-path "/groupB/groupC"
+
+         If there are multiple paths to an object, only the specified path(s)
+         will be excluded; the comparison will include any path not explicitly
+         excluded.
+         This option can be used repeatedly to exclude multiple paths.
+
+ Modes of output:
+  Default mode: print the number of differences found and where they occured
+  -r Report mode: print the above plus the differences
+  -v Verbose mode: print the above plus a list of objects and warnings
+  -q Quiet mode: do not print output
+
+ File comparison:
+  If no objects [obj1[ obj2]] are specified, the h5diff comparison proceeds as
+  a comparison of the two files' root groups.  That is, h5diff first compares
+  the names of root group members, generates a report of root group objects
+  that appear in only one file or in both files, and recursively compares
+  common objects.
+
+ Object comparison:
+  1) Groups 
+      First compares the names of member objects (relative path, from the
+      specified group) and generates a report of objects that appear in only
+      one group or in both groups. Common objects are then compared recursively.
+  2) Datasets 
+      Array rank and dimensions, datatypes, and data values are compared.
+  3) Datatypes 
+      The comparison is based on the return value of H5Tequal.
+  4) Symbolic links 
+      The paths to the target objects are compared.
+      (The option --follow-symlinks overrides the default behavior when
+       symbolic links are compared.).
+
+ Exit code:
+  0 if no differences, 1 if differences found, 2 if error
+
+ Examples of use:
+ 1) h5diff file1 file2 /g1/dset1 /g1/dset2
+    Compares object '/g1/dset1' in file1 with '/g1/dset2' in file2
+
+ 2) h5diff file1 file2 /g1/dset1
+    Compares object '/g1/dset1' in both files
+
+ 3) h5diff file1 file2
+    Compares all objects in both files
+
+ Notes:
+  file1 and file2 can be the same file.
+  Use h5diff file1 file1 /g1/dset1 /g1/dset2 to compare
+  '/g1/dset1' and '/g1/dset2' in the same file

+         link (a soft or external link pointing to a target object that does
+         not yet exist).
+         - If both symbolic links are dangling links, they are treated as being

+         Must be used with --follow-symlinks option; otherwise, h5diff shows

+         Check for any symbolic links (soft links or external links) that do not

+   --use-system-epsilon
+         Print difference if (|a-b| > EPSILON), EPSILON is system defined value.
+         If the system epsilon is not defined,one of the following predefined
+         values will be used:
+           FLT_EPSILON = 1.19209E-07 for floating-point type

+         Can not use with '-p' or '-d'.
+   --exclude-path "path" 
+         Exclude the specified path to an object when comparing files or groups.
+         If a group is excluded, all member objects will also be excluded.
+         The specified path is excluded wherever it occurs.
+         This flexibility enables the same option to exclude either objects that
+         exist only in one file or common objects that are known to differ.
+
+         When comparing files, "path" is the absolute path to the excluded;
+         object; when comparing groups, "path" is similar to the relative
+         path from the group to the excluded object. This "path" can be
+         taken from the first section of the output of the --verbose option.
+         For example, if you are comparing the group /groupA in two files and
+         you want to exclude /groupA/groupB/groupC in both files, the exclude
+         option would read as follows:
+           --exclude-path "/groupB/groupC"
+
+         If there are multiple paths to an object, only the specified path(s)
+         will be excluded; the comparison will include any path not explicitly
+         excluded.
+         This option can be used repeatedly to exclude multiple paths.
+
+ Modes of output:
+  Default mode: print the number of differences found and where they occured
+  -r Report mode: print the above plus the differences
+  -v Verbose mode: print the above plus a list of objects and warnings
+  -q Quiet mode: do not print output
+
+ File comparison:
+  If no objects [obj1[ obj2]] are specified, the h5diff comparison proceeds as
+  a comparison of the two files' root groups.  That is, h5diff first compares
+  the names of root group members, generates a report of root group objects
+  that appear in only one file or in both files, and recursively compares
+  common objects.
+
+ Object comparison:
+  1) Groups 
+      First compares the names of member objects (relative path, from the
+      specified group) and generates a report of objects that appear in only
+      one group or in both groups. Common objects are then compared recursively.
+  2) Datasets 
+      Array rank and dimensions, datatypes, and data values are compared.
+  3) Datatypes 
+      The comparison is based on the return value of H5Tequal.
+  4) Symbolic links 
+      The paths to the target objects are compared.
+      (The option --follow-symlinks overrides the default behavior when
+       symbolic links are compared.).
+
+ Exit code:
+  0 if no differences, 1 if differences found, 2 if error
+
+ Examples of use:
+ 1) h5diff file1 file2 /g1/dset1 /g1/dset2
+    Compares object '/g1/dset1' in file1 with '/g1/dset2' in file2
+
+ 2) h5diff file1 file2 /g1/dset1
+    Compares object '/g1/dset1' in both files
+
+ 3) h5diff file1 file2
+    Compares all objects in both files
+
+ Notes:
+  file1 and file2 can be the same file.
+  Use h5diff file1 file1 /g1/dset1 /g1/dset2 to compare
+  '/g1/dset1' and '/g1/dset2' in the same file

+         Follow symbolic links (soft links and external links and compare the)
+         links' target objects.
+         If symbolic link(s) with the same name exist in the files being
+         compared, then determine whether the target of each link is an existing
+         object (dataset, group, or named datatype) or the link is a dangling
+         link (a soft or external link pointing to a target object that does
+         not yet exist).
+         - If both symbolic links are dangling links, they are treated as being
+           the same; by default, h5diff returns an exit code of 0.
+           If, however, --no-dangling-links is used with --follow-symlinks,
+           this situation is treated as an error and h5diff returns an
+           exit code of 2.
+         - If only one of the two links is a dangling link,they are treated as
+           being different and h5diff returns an exit code of 1.
+           If, however, --no-dangling-links is used with --follow-symlinks,
+           this situation is treated as an error and h5diff returns an
+           exit code of 2.
+         - If both symbolic links point to existing objects, h5diff compares the
+           two objects.
+         If any symbolic link specified in the call to h5diff does not exist,
+         h5diff treats it as an error and returns an exit code of 2.
+   --no-dangling-links
+         Must be used with --follow-symlinks option; otherwise, h5diff shows
+         error message and returns an exit code of 2.
+         Check for any symbolic links (soft links or external links) that do not
+         resolve to an existing object (dataset, group, or named datatype).
+         If any dangling link is found, this situation is treated as an error
+         and h5diff returns an exit code of 2.
+   -c, --compare
+         List objects that are not comparable
+   -N, --nan
+         Avoid NaNs detection
+   -n C, --count=C
+         Print differences up to C. C must be a positive integer.
+   -d D, --delta=D
+         Print difference if (|a-b| > D). D must be a positive number.
+         Can not use with '-p' or '--use-system-epsilon'.
+   -p R, --relative=R
+         Print difference if (|(a-b)/b| > R). R must be a positive number.
+         Can not use with '-d' or '--use-system-epsilon'.
+   --use-system-epsilon
+         Print difference if (|a-b| > EPSILON), EPSILON is system defined value.
+         If the system epsilon is not defined,one of the following predefined
+         values will be used:
+           FLT_EPSILON = 1.19209E-07 for floating-point type
+           DBL_EPSILON = 2.22045E-16 for double precision type
+         Can not use with '-p' or '-d'.
+   --exclude-path "path" 
+         Exclude the specified path to an object when comparing files or groups.
+         If a group is excluded, all member objects will also be excluded.
+         The specified path is excluded wherever it occurs.
+         This flexibility enables the same option to exclude either objects that
+         exist only in one file or common objects that are known to differ.
+
+         When comparing files, "path" is the absolute path to the excluded;
+         object; when comparing groups, "path" is similar to the relative
+         path from the group to the excluded object. This "path" can be
+         taken from the first section of the output of the --verbose option.
+         For example, if you are comparing the group /groupA in two files and
+         you want to exclude /groupA/groupB/groupC in both files, the exclude
+         option would read as follows:
+           --exclude-path "/groupB/groupC"
+
+         If there are multiple paths to an object, only the specified path(s)
+         will be excluded; the comparison will include any path not explicitly
+         excluded.
+         This option can be used repeatedly to exclude multiple paths.
+
+ Modes of output:
+  Default mode: print the number of differences found and where they occured
+  -r Report mode: print the above plus the differences
+  -v Verbose mode: print the above plus a list of objects and warnings
+  -q Quiet mode: do not print output
+
+ File comparison:
+  If no objects [obj1[ obj2]] are specified, the h5diff comparison proceeds as
+  a comparison of the two files' root groups.  That is, h5diff first compares
+  the names of root group members, generates a report of root group objects
+  that appear in only one file or in both files, and recursively compares
+  common objects.
+
+ Object comparison:
+  1) Groups 
+      First compares the names of member objects (relative path, from the
+      specified group) and generates a report of objects that appear in only
+      one group or in both groups. Common objects are then compared recursively.
+  2) Datasets 
+      Array rank and dimensions, datatypes, and data values are compared.
+  3) Datatypes 
+      The comparison is based on the return value of H5Tequal.
+  4) Symbolic links 
+      The paths to the target objects are compared.
+      (The option --follow-symlinks overrides the default behavior when
+       symbolic links are compared.).
+
+ Exit code:
+  0 if no differences, 1 if differences found, 2 if error
+
+ Examples of use:
+ 1) h5diff file1 file2 /g1/dset1 /g1/dset2
+    Compares object '/g1/dset1' in file1 with '/g1/dset2' in file2
+
+ 2) h5diff file1 file2 /g1/dset1
+    Compares object '/g1/dset1' in both files
+
+ 3) h5diff file1 file2
+    Compares all objects in both files
+
+ Notes:
+  file1 and file2 can be the same file.
+  Use h5diff file1 file1 /g1/dset1 /g1/dset2 to compare
+  '/g1/dset1' and '/g1/dset2' in the same file

+         If the system epsilon is not defined,one of the following predefined
+         values will be used:
+           FLT_EPSILON = 1.19209E-07 for floating-point type

+         Can not use with '-p' or '-d'.
+   --exclude-path "path" 
+         Exclude the specified path to an object when comparing files or groups.
+         If a group is excluded, all member objects will also be excluded.
+         The specified path is excluded wherever it occurs.
+         This flexibility enables the same option to exclude either objects that
+         exist only in one file or common objects that are known to differ.
+
+         When comparing files, "path" is the absolute path to the excluded;
+         object; when comparing groups, "path" is similar to the relative
+         path from the group to the excluded object. This "path" can be
+         taken from the first section of the output of the --verbose option.
+         For example, if you are comparing the group /groupA in two files and
+         you want to exclude /groupA/groupB/groupC in both files, the exclude
+         option would read as follows:
+           --exclude-path "/groupB/groupC"
+
+         If there are multiple paths to an object, only the specified path(s)
+         will be excluded; the comparison will include any path not explicitly
+         excluded.
+         This option can be used repeatedly to exclude multiple paths.
+
+ Modes of output:
+  Default mode: print the number of differences found and where they occured
+  -r Report mode: print the above plus the differences
+  -v Verbose mode: print the above plus a list of objects and warnings
+  -q Quiet mode: do not print output
+
+ File comparison:
+  If no objects [obj1[ obj2]] are specified, the h5diff comparison proceeds as
+  a comparison of the two files' root groups.  That is, h5diff first compares
+  the names of root group members, generates a report of root group objects
+  that appear in only one file or in both files, and recursively compares
+  common objects.
+
+ Object comparison:
+  1) Groups 
+      First compares the names of member objects (relative path, from the
+      specified group) and generates a report of objects that appear in only
+      one group or in both groups. Common objects are then compared recursively.
+  2) Datasets 
+      Array rank and dimensions, datatypes, and data values are compared.
+  3) Datatypes 
+      The comparison is based on the return value of H5Tequal.
+  4) Symbolic links 
+      The paths to the target objects are compared.
+      (The option --follow-symlinks overrides the default behavior when
+       symbolic links are compared.).
+
+ Exit code:
+  0 if no differences, 1 if differences found, 2 if error
+
+ Examples of use:
+ 1) h5diff file1 file2 /g1/dset1 /g1/dset2
+    Compares object '/g1/dset1' in file1 with '/g1/dset2' in file2
+
+ 2) h5diff file1 file2 /g1/dset1
+    Compares object '/g1/dset1' in both files
+
+ 3) h5diff file1 file2
+    Compares all objects in both files
+
+ Notes:
+  file1 and file2 can be the same file.
+  Use h5diff file1 file1 /g1/dset1 /g1/dset2 to compare
+  '/g1/dset1' and '/g1/dset2' in the same file

+         If symbolic link(s) with the same name exist in the files being

+         link (a soft or external link pointing to a target object that does
+         not yet exist).
+         - If both symbolic links are dangling links, they are treated as being

+           If, however, --no-dangling-links is used with --follow-symlinks,

+           If, however, --no-dangling-links is used with --follow-symlinks,
+           this situation is treated as an error and h5diff returns an
+           exit code of 2.
+         - If both symbolic links point to existing objects, h5diff compares the

+         If any symbolic link specified in the call to h5diff does not exist,
+         h5diff treats it as an error and returns an exit code of 2.
+   --no-dangling-links
+         Must be used with --follow-symlinks option; otherwise, h5diff shows
+         error message and returns an exit code of 2.
+         Check for any symbolic links (soft links or external links) that do not

+   --use-system-epsilon
+         Print difference if (|a-b| > EPSILON), EPSILON is system defined value.
+         If the system epsilon is not defined,one of the following predefined

+   --exclude-path "path" 
+         Exclude the specified path to an object when comparing files or groups.
+         If a group is excluded, all member objects will also be excluded.
+         The specified path is excluded wherever it occurs.
+         This flexibility enables the same option to exclude either objects that
+         exist only in one file or common objects that are known to differ.
+
+         When comparing files, "path" is the absolute path to the excluded;
+         object; when comparing groups, "path" is similar to the relative
+         path from the group to the excluded object. This "path" can be
+         taken from the first section of the output of the --verbose option.
+         For example, if you are comparing the group /groupA in two files and
+         you want to exclude /groupA/groupB/groupC in both files, the exclude
+         option would read as follows:
+           --exclude-path "/groupB/groupC"
+
+         If there are multiple paths to an object, only the specified path(s)
+         will be excluded; the comparison will include any path not explicitly
+         excluded.
+         This option can be used repeatedly to exclude multiple paths.

+ *   Four more datasets of 1, 2, 4 and 8 bytes of signed int types are created.
+ *   Fill them with raw data such that no bit will be all zero in a dataset.
+ *   A dummy dataset of double type is created for failure test.
+ *   Use file to test Signed/Unsigned datatypes and keep in sync with gent_packedbits()

+OPTIONS
+  -i in_file.h5    Specifies the input HDF5 file.
+  -u in_user_file  Specifies the file to be inserted into the user block.
+                   Can be any file format except an HDF5 format.
+  -o out_file.h5   Specifies the output HDF5 file.
+                   If not specified, the user block will be concatenated in
+                   place to the input HDF5 file.
+  --clobber        Wipes out any existing user block before concatenating
+                   the given user block.
+                   The size of the new user block will be the larger of;
+                    - the size of existing user block in the input HDF5 file
+                    - the size of user block required by new input user file
+                   (size = 512 x 2N,  N is positive integer.)
+
+  -h               Prints a usage message and exits.
+  -V               Prints the HDF5 library version and exits.

+    U - is a filename.
+    T - is an integer
+    A - is an integer greater than zero
+    B - is the user block size, any value that is 512 or greater and is
+        a power of 2 (1024 default)

+
+     --enable-error-stack Prints messages from the HDF5 error stack as they
+                          occur.
+
+    FS_STRATEGY is a string indicating the file space strategy used:
+        FSM_AGGR:
+               The mechanisms used in managing file space are free-space managers, aggregators and virtual file driver.
+        PAGE:
+               The mechanisms used in managing file space are free-space managers with embedded paged aggregation and virtual file driver.
+        AGGR:
+               The mechanisms used in managing file space are aggregators and virtual file driver.
+        NONE:
+               The mechanisms used in managing file space are virtual file driver.
+        The default strategy when not set is FSM_AGGR without persisting free-space.
+
+    FS_PERSIST is 1 to persisting free-space or 0 to not persisting free-space.
+      The default when not set is not persisting free-space.
+      The value is ignored for AGGR and NONE strategies.
+
+    FS_THRESHOLD is the minimum size (in bytes) of free-space sections to be tracked by the library.
+      The default when not set is 1.
+      The value is ignored for AGGR and NONE strategies.
+
+    FS_PAGESIZE is the size (in bytes) >=512 that is used by the library when the file space strategy PAGE is used.
+      The default when not set is 4096.
+
+    FILT - is a string with the format:
+
+      <list of objects>:<name of filter>=<filter parameters>
+
+      <list of objects> is a comma separated list of object names, meaning apply
+        compression only to those objects. If no names are specified, the filter
+        is applied to all objects
+      <name of filter> can be:
+        GZIP, to apply the HDF5 GZIP filter (GZIP compression)
+        SZIP, to apply the HDF5 SZIP filter (SZIP compression)
+        SHUF, to apply the HDF5 shuffle filter
+        FLET, to apply the HDF5 checksum filter
+        NBIT, to apply the HDF5 NBIT filter (NBIT compression)
+        SOFF, to apply the HDF5 Scale/Offset filter
+        UD,   to apply a user defined filter
+        NONE, to remove all filters
+      <filter parameters> is optional filter parameter information
+        GZIP=<deflation level> from 1-9
+        SZIP=<pixels per block,coding> pixels per block is a even number in
+            2-32 and coding method is either EC or NN
+        SHUF (no parameter)
+        FLET (no parameter)
+        NBIT (no parameter)
+        SOFF=<scale_factor,scale_type> scale_factor is an integer and scale_type
+            is either IN or DS
+        UD=<filter_number,cd_value_count,value_1[,value_2,...,value_N]>
+            required values for filter_number,cd_value_count,value_1
+            optional values for value_2 to value_N
+        NONE (no parameter)
+
+    LAYT - is a string with the format:
+
+      <list of objects>:<layout type>=<layout parameters>
+
+      <list of objects> is a comma separated list of object names, meaning that
+        layout information is supplied for those objects. If no names are
+        specified, the layout type is applied to all objects
+      <layout type> can be:
+        CHUNK, to apply chunking layout
+        COMPA, to apply compact layout
+        CONTI, to apply contiguous layout
+      <layout parameters> is optional layout information
+        CHUNK=DIM[xDIM...xDIM], the chunk size of each dimension
+        COMPA (no parameter)
+        CONTI (no parameter)
+
+Examples of use:
+
+1) h5repack -v -f GZIP=1 file1 file2
+
+   GZIP compression with level 1 to all objects
+
+2) h5repack -v -f dset1:SZIP=8,NN file1 file2
+
+   SZIP compression with 8 pixels per block and NN coding method to object dset1
+
+3) h5repack -v -l dset1,dset2:CHUNK=20x10 -f dset3,dset4,dset5:NONE file1 file2
+
+   Chunked layout, with a layout size of 20x10, to objects dset1 and dset2
+   and remove filters to objects dset3, dset4, dset5
+
+4) h5repack -L -c 10 -s 20:dtype file1 file2 
+
+   Using latest file format with maximum compact group size of 10 and
+   and minimum shared datatype size of 20
+
+5) h5repack -f SHUF -f GZIP=1 file1 file2 
+
+   Add both filters SHUF and GZIP in this order to all datasets
+
+6) h5repack -f UD=307,1,9 file1 file2 
+
+   Add bzip2 filter to all datasets

+ *		The library will not check status_flags when opening a file
