#   The SunOS 5.6 sed *must* have slashes as delimiters. I changed things like
#   `sed s+/CVS++' to `sed 's/\/CVS//'
#
#   Albert Cheng, 1999-10-26
#   Moved the MANIFEST checking to a separate command file so that
#   it can be invoked individually.
#
#   Albert Cheng, 2004-08-14
#   Added the --private option.
#
#   James Laird, 2005-09-07
#   Added the md5 method.
#
#   Larry Knox, 2017-06-16
#   Added cmake-tgz and cmake-zip methods
#   Replaced optional md5 method with automatic md5 checksum generation for
#   all archives (from hdf5 release script)

USAGE()
{
cat << EOF
Usage: $0 -d <dir> [-h] [--nocheck] [--private] <methods> ...
   -d <dir>	The name of the directory where the releas(es) should be
                placed.
   -h           print the help page.
   --nocheck	Ignore errors in MANIFEST file.
   --private	Make a private release with today's date in version information.
         
This must be run at the top level of the source directory.
The other command-line options are the names of the programs to use
for compressing the resulting tar archive (if none are given then
"tar md5" is assumed):
    tar		-- use tar and don't do any compressing.
    gzip	-- use gzip with "-9" and append ".gz" to the output name.
    cmake-tgz   -- create a tar file using the gzip default level with a 
                   build-unix.sh command file and all other CMake files needed 
                   to build HDF4 source using CMake on unix machines.
    bzip2       -- use bzip2 with "-9" and append ".bz2" to the output name.
    zip		-- convert all text files to DOS style and form a zip file for 
                   Windows use.
    cmake-zip   -- convert all text files to DOS style and create a zip file 
                   including cmake scripts and .bat files to build HDF4 source 
                   using CMake on Windows.

An md5 checksum is produced for each archive created and stored in the md5 file.

Examples:

    $ bin/release -d /tmp
    /tmp/hdf-4.2.11-RELEASE.txt
    /tmp/hdf-4.2.11.md5
    /tmp/hdf-4.2.11.tar

    $ bin/release -d /tmp gzip
    /tmp/hdf-4.2.11-RELEASE.txt
    /tmp/hdf-4.2.11.md5
    /tmp/hdf-4.2.11.tar.gz

    $ bin/release -d /tmp tar gzip zip
    /tmp/hdf-4.2.11-RELEASE.txt
    /tmp/hdf-4.2.11.md5
    /tmp/hdf-4.2.11.tar
    /tmp/hdf-4.2.11.tar.gz
    /tmp/hdf-4.2.11.zip

# Convert the release tarball to a Windows zipball.

# 1. untar the tarball in a temporay directory;

#    the original source directory which maybe around.
# 2. convert all its text files to DOS (LF-CR) style;
# 3. form a zip file which is usable by Windows users.

# Parameters:
# $1 version
# $2 release tarball
# $3 output zipball file name
#
# Returns 0 if successful; 1 otherwise
