28--help This help.
29--prefix=DIR Prefix where LuaRocks should be installed.
30 Default is $PREFIX
31--sysconfdir=DIR Location where the config file should be installed.
32 Default is \$PREFIX/etc/luarocks
33--rocks-tree=FILE Root of the local tree of installed rocks.
34 Default is \$PREFIX/lib/luarocks
35--scripts-dir=DIR Where to install scripts installed by rocks.
36 Default is \$ROCKS_TREE/bin. Use this if you
37 want to modify it so that rocks install scripts
38 somewhere else (possibly somewhere in your \$PATH),
39 but if you use a system path such as /usr/bin,
40 beware of clashes between files installed by
41 LuaRocks and by your system's package manager.
42 Example: /usr/local/bin
43--lua-suffix=SUFFIX Versioning suffix to use in Lua filenames.
44 Default is "$LUA_SUFFIX" (lua$LUA_SUFFIX...)
45--with-lua=PREFIX Use Lua from given prefix.
46 Default is $LUA_DIR
47--with-lua-include=DIR You can also specify Lua's includes dir.
48 Default is \$LUA_DIR/include
49--with-lua-lib=DIR You can also specify Lua's libraries dir.
50 Default is \$LUA_DIR/lib
51--with-downloader=TOOL Which tool to use as a downloader.
52 Valid options are: wget, curl.
53 Default is to auto-detect.
54--with-md5-checker=TOOL Which tool to use as a downloader.
55 Valid options are: md5sum, openssl
56 Default is to auto-detect.
57--force-config Use a single config location. Do not use the
58 \$LUAROCKS_CONFIG variable or the user's home
59 directory. Useful to avoid conflicts when LuaRocks
60 is embedded within an application.
