#

### Purpose
# Increments the hdf5 version number by changing the value of
# constants in the src/H5public.h file.  The new version number is
# printed on the standard output. An alternate source file name can be
# specified as an argument.  In any case, the original file is saved
# by appending a tilde `~' to the name.

### Usage:
# h5vers [OPTIONS] [FILE]

# Without options this program only displays the current version and
# doesn't modify any files or create backups.  The default is to print
# the version number like X.Y.Z-A where X is the major version number,
# Y is the minor version number, Z is the release number, and A is
# a short annotation string (the `-' is printed only if A is not empty).
# If the `-v' switch is given the version will be printed like:
#
#    version X.Y release Z (A)
#
# The space and parentheses around A are only printed if A is not empty.
#
# The `-s VERSION' switch will set the version as specified.  If the
# string contains a dotted triple then it will be used as the version
# number, otherwise up to three numbers will be read from the end of
# the string and used as the major version, minor version, and release
# number.  If any numbers are missing then zero is assumed.  This
# allows versions to be specified like `-s "version 2.1 release 8"' or
# `-s hdf5-2.1.8.tar.bz2'.  If the new version is less than the old
# version then a warning message is generated on standard error. The
# annotation string, A, is set only if it appears immediately after the
# third number, separated by a dash (e.g., `1.2.3-pre1') or in parentheses
# (e.g., `version 1.2 release 3 (pre1)').
#
# The `-i [major|minor|release|annot|last]' option increments the major
# number, minor number, release number, or annotation string. The `last'
# switch increments the annotation string if present, otherwise the
# release number. If the release number is incremented then the annotation
# string is cleared.  If the minor number is incremented then the release
# number is set to zero and the annotation string is cleared; if the major
# number is incremented then the minor and release numbers are set to zero
# and the annotation string is cleared.
#
# If a file is specified then that file is used instead of
# ./H5public.h or ./src/H5public.h.
#
# If the version number is changed (either `-s' or `-i' was used on
# the command line) then the version line of the README.md and RELEASE.txt files
# one directory above the H5public.h file is also modified so it looks
# something like: This is hdf5-1.2.3-pre1 currently under development.
# The AC_INIT macro in configure.ac will also change in this case to be
# something like: AC_INIT([HDF5], [hdf5-1.2.3-pre1], [help@hdfgroup.org])
# Version changes are also reflected in the Windows-maintained H5pubconf.h
# file.
#
# Whenever the version changes, this script will increment the revision
# field in HDF5's libtool shared library version in config/lt_vers.am,
# which is included in src/Makefile.am.  Incrementing the revision field
# indicates that the source code has changed since the last version
# (which it probably has).

        Set the version as specified. The version number can be embedded in
