When running "init --update-version" command, llvmenv get version information about LLVM/Clang/Compiler-rt/LLDB/Clang-extra-tools using "svn ls" command.
Now, you will be able to specify the version when execute install command.

The "list --all" command show available version to install.

llvmenv list --all

llvmenv list

You can install llvm/clang with "install" subcommand.
If you specify options with "--opt" option, that parameter is used as configure parameter except prefix.
But, install target directory is defined in llvmenv, so prefix option is ignored whenever you specify it with "--opt".

# DEBUG build
llvmenv install RELEASE_361.final --delete-src=false --delete-build=false --disable-optimized --enable-assertions

The install sub-command has options described in bellow.

The "use" sub-command enable specified llvm/clang version to use.

You can uninstall llvm/clang with following command.

llvmenv uninstall RELEASE_361.final
