:: File Name: hdf5build.bat
:: This batch file is used to build HDF5 Libraries and Tools.
:: There are currently only 2 options for this batch file:
::   1. hdf5build                -- Print a usage message and quit
::   1. hdf5build                -- Build HDF5 tools and c library
:: By Xuan Bai
:: Created: Aug. 16, 2004
:: Last Updated: July 13, 2007

:: This batch file makes the following assumptions:
::    - The appropriate version of Visual Studio is installed and setup
::    - The directory structure is setup from a fresh source copy
::    - copy_hdf.bat has already been run from the ./windows directory
::    - Visual Studio already contains the required paths for external libraries
::    - szip and zlib DLLs are already placed in an accessible directory
::    - If hdf5_ext_szip or hdf5_ext_zlib are not set, then %szip_name% and %zlib_name%
::      will be used, respectively.

:: By default, only C and C++ libraries are built.
