Configure LuaRocks.

--help                      This help.
--prefix=DIR                Prefix where LuaRocks should be installed.
                            Default is $PREFIX
--sysconfdir=DIR            Location where the config file should be installed.
                            Default is \$PREFIX/etc/luarocks

Where to install files installed by rocks, to make the accessible to Lua and
your \$PATH. Beware of clashes between files installed by LuaRocks and by your
system's package manager.

--rocks-tree=DIR            Root of the local tree of installed rocks.
                            Default is \$PREFIX

--lua-version=VERSION       Use specific Lua version: 5.1, 5.2, or 5.3
                            Default is auto-detected.
--lua-suffix=SUFFIX         Versioning suffix to use in Lua filenames.
                            Default is "$LUA_SUFFIX" (lua$LUA_SUFFIX...)
--with-lua=PREFIX           Use Lua from given prefix.
                            Default is auto-detected (the parent directory of \$LUA_BINDIR).
--with-lua-bin=DIR          You can also specify Lua's bin dir.
                            Default is the directory of the auto-detected Lua interpreter,
                            or \$LUA_DIR/bin if --with-lua is used.
--with-lua-include=DIR      You can also specify Lua's includes dir.
                            Default is \$LUA_DIR/include
--with-lua-lib=DIR          You can also specify Lua's libraries dir.
                            Default is \$LUA_DIR/lib
--with-downloader=TOOL      Which tool to use as a downloader.
                            Valid options are: curl, wget.
                            Default is to auto-detect.
--with-md5-checker=TOOL     Which tool to use as a downloader.
                            Valid options are: md5sum, openssl
                            Default is to auto-detect.
--versioned-rocks-dir       Use a versioned rocks dir, such as
                            \$PREFIX/lib/luarocks/rocks-$LUA_VERSION/.
                            Default is to auto-detect the necessity.
--force-config              Use a single config location. Do not use the
                            \$LUAROCKS_CONFIG variable or the user's home
                            directory. Useful to avoid conflicts when LuaRocks
                            is embedded within an application.
