### Copyright © 1998 NCSA.
# Robb Matzke <matzke@llnl.gov>
# 17 July 1998
### 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 as a dotted triple like `1.0.24' but with the
# `-v' option the version will be printed as `version 1.0 release 24'.
#
# 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 `-i [major|minor|release]' option increments the major, minor,
# or release (the default) number. If the minor number is incremented
# then the release number is set to zero; if the major number is
# incremented then the minor and release numbers are set to zero.
#
# If a file is specified then that file is used instead of
# ./H5public.h or ./src/H5public.h.

Usage: $prog [OPTS] [FILE]
-i major|minor|release
Increment specified version component and set following components
to zero.
-s VERSION
Set the version as specified. The version number can be embedded in
some other string such as \"hdf5-1.1.0.tar.bz2\" or even \"this is
hdf5 version 1.1 release 0\" for convenience.
-v
Instead of displaying only a dotted triple version number a line such
as \"version 1.1 release 0\" will be printed.
FILE
The name of the file that contains version information. This is
seldom necessary since files H5public.h, src/H5public.h and
../src/H5public.h are automatically checked.
