# Script to build and install libbitcoin.
#
# Script options:
# --build-gmp              Builds GMP library.
# --build-boost            Builds Boost libraries.
# --build-dir=<path>       Location of downloaded and intermediate files.
# --prefix=<absolute-path> Library install location (defaults to /usr/local).
# --disable-shared         Disables shared library builds.
# --disable-static         Disables static library builds.
#
# Verified on Ubuntu 14.04, requires gcc-4.8 or newer.
# Verified on OSX 10.10, using MacPorts and Homebrew repositories, requires
# Apple LLVM version 6.0 (clang-600.0.54) (based on LLVM 3.5svn) or newer.
# This script does not like spaces in the --prefix or --build-dir, sorry.
# Values (e.g. yes|no) in the boolean options are not supported by the script.
# All command line options are passed to 'configure' of each repo, with
# the exception of the --build-<item> options, which are for the script only.
# Depending on the caller's permission to the --prefix or --build-dir
# directory, the script may need to be sudo'd.

# Define common values.
