Usage: $0 -d <dir> [--docver BRANCHNAME] [-h] [--nocheck] [--private] <methods> ...
   -d DIR	The name of the directory where the releas(es) should be
                placed.
   --docver BRANCHNAME  This is added for 1.8 and beyond to get the correct
                        version of documentation files from the hdf5docs
                        repository.  BRANCHNAME for v1.8 should be hdf5_1_8.
   -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" 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 HDF5 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 inluding cmake
                   scripts and .bat files to build HDF5 source using CMake on Windows. 
    doc         -- produce the latest doc tree in addition to the archive.

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

Examples:

    $ bin/release -d /tmp
    /tmp/hdf5-1.8.13-RELEASE.txt
    /tmp/hdf5-1.8.13.md5
    /tmp/hdf5-1.8.13.tar

    $ bin/release -d /tmp gzip
    /tmp/hdf5-1.8.13-RELEASE.txt
    /tmp/hdf5-1.8.13.md5
    /tmp/hdf5-1.8.13.tar.gz

    $ bin/release -d /tmp tar gzip zip
    /tmp/hdf5-1.8.13-RELEASE.txt
    /tmp/hdf5-1.8.13.md5
    /tmp/hdf5-1.8.13.tar
    /tmp/hdf5-1.8.13.tar.gz

# Function name: tar2zip
# Convert the release tarball to a Windows zipball.

# Steps:
# 1. untar the tarball in a temporary directory;
#    Note: do this in a temporary directory to avoid changing
#    the original source directory which may be 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
