${prog} [<options>]

<options> can be one of the following:

--prefix=<val>		The installation prefix (default: /usr).
--enable-debug		Enable debug mode compilation (default: disabled).
--disable-allocator	Disable use of internal memory allocator mechanism (default: enabled).
--enable-debug-stats	Enable printing of some verbose debug info (default: disabled).
--with-openssl=<path to OpenSSL installation tree> (Default: System)
			This defaults to the system's OpenSSL library. You can use this option
			if you want to use an alternate OpenSSL installation.
--with-zlib=<path to zlib installation tree> (Default: System)
			Enable building against an alternate Zlib installation.
--with-bzlib=<path to Bzip2 library installation tree> (Default: System)
			Enable building against an alternate Bzip2 and library installation.
--with-external-libbsc=<path to libbsc source tree>
			Enable building with exernal libbsc sources. Can be used to link with
			ASLv2 libbsc when using MPLv2 licensed sources.
--wavpack-dir=<path to WavPack source tree>
			Points to the directory containing the WavPack sources. This option
			must be specified if --disable-wavpack is not provided.
--disable-wavpack	Disables the WavPack filter.
--no-sse-detect		Do NOT attempt to probe the system's SSE capability for build flags.
			Implies '--no-avx-detect' below.
--no-avx-detect		Do NOT attempt to probe the system's AVX capability for build flags.
--no-1.3-archive-compat Disable compatibility with compressed archives created with Pcompress
			version 1.3 (default: retain compatibility). Hash formats changed from
			version 1.3 to 1.4 so this option is required if files created using
			1.3 need to be decompressed by version 1.4 onwards.
--limit-key128		Limit key length to 128-bit encryption keys. Otherwise the default is to
			use 256-bit keys changeable at runtime via the '-k <keylen>' option.
--help			Display this help message.
