+Configure LuaRocks.
+
+--help                      This help.
+--prefix=DIR                Prefix where LuaRocks should be installed.
+                            Default is $PREFIX
+--sysconfdir=DIR            Location where the config file should be installed.
+                            Default is \$PREFIX/etc/luarocks
+--rocks-tree=FILE           Root of the local tree of installed rocks.
+                            Default is \$PREFIX/lib/luarocks
+--scripts-dir=DIR           Where to install scripts installed by rocks.
+                            Default is \$ROCKS_TREE/bin. Use this if you
+                            want to modify it so that rocks install scripts
+                            somewhere else (possibly somewhere in your \$PATH),
+                            but if you use a system path such as /usr/bin,
+                            beware of clashes between files installed by
+                            LuaRocks and by your system's package manager.
+                            Example: /usr/local/bin
+--lua-suffix=SUFFIX         Versioning suffix to use in Lua filenames.
+                            Default is "$LUA_SUFFIX" (lua$LUA_SUFFIX...)
+--with-lua=PREFIX           Use Lua from given prefix.
+                            Default is $LUA_DIR
+--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: wget, curl.
+                            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.
+--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.
