usage (void)
{
fprintf(stderr, "\
usage: %s [OPTIONS] [OBJECTS...]\n\
OPTIONS\n\
-h, -?, --help Print a usage message and exit\n\
-a, --address Print raw data address. If dataset is contiguous, address\n\
is offset in file of beginning of raw data. If chunked,\n\
returned list of addresses indicates offset of each chunk.\n\
Must be used with -v, --verbose option.\n\
Provides no information for non-dataset objects.\n\
-d, --data Print the values of datasets\n\
--enable-error-stack\n\
Prints messages from the HDF5 error stack as they occur.\n\
--follow-symlinks\n\
Follow symbolic links (soft links and external links)\n\
to display target object information.\n\
Without this option, h5ls identifies a symbolic link\n\
as a soft link or external link and prints the value\n\
assigned to the symbolic link; it does not provide any\n\
information regarding the target object or determine\n\
whether the link is a dangling link.\n\
--no-dangling-links\n\
Must be used with --follow-symlinks option;\n\
otherwise, h5ls shows error message and returns an exit\n\
code of 1. \n\
Check for any symbolic links (soft links or external links)\n\
that do not resolve to an existing object (dataset, group,\n\
or named datatype).\n\
If any dangling link is found, this situation is treated\n\
as an error and h5ls returns an exit code of 1.\n\
-f, --full Print full path names instead of base names\n\
-g, --group Show information about a group, not its contents\n\
-l, --label Label members of compound datasets\n\
-r, --recursive List all groups recursively, avoiding cycles\n\
-s, --string Print 1-byte integer datasets as ASCII\n\
-S, --simple Use a machine-readable output format\n\
-wN, --width=N Set the number of columns of output\n\
-v, --verbose Generate more verbose output\n\
-V, --version Print version number and exit\n\
--vfd=DRIVER Use the specified virtual file driver\n\
-x, --hexdump Show raw data in hexadecimal format\n\
\n\
OBJECTS\n\
Each object consists of an HDF5 file name optionally followed by a\n\
slash and an object name within the file (if no object is specified\n\
within the file then the contents of the root group are displayed).\n\
The file name may include a printf(3C) integer format such as\n\
\"%%05d\" to open a file family.\n\
\n\
Deprecated Options\n\
The following options have been deprecated in HDF5. While they remain\n\
available, they have been superseded as indicated and may be removed\n\
from HDF5 in the future. Use the indicated replacement option in all\n\
new work; where possible, existing scripts, et cetera, should also be\n\
updated to use the replacement option.\n\
\n\
-E or --external Follow external links.\n\
Replaced by --follow-symlinks.\n\
-e, --errors Show all HDF5 error reporting\n\
Replaced by --enable-error-stack.\n",
