${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-libarchive=<path to libarchive installation tree> (Default: System)
Enable building against an alternate libarchive 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.
--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.
