Getting Started
====================
Download
--------------------
Getting spack is easy. You can clone it from the `github repository
<https://github.com/scalability-llnl/spack>`_ using this command:
.. code-block:: sh
$ git clone https://github.com/scalability-llnl/spack.git
This will create a directory called ``spack``. We'll assume that the
full path to this directory is in some environment called
``SPACK_HOME``. Add ``$SPACK_HOME/bin`` to your path and you're ready
to go:
.. code-block:: sh
$ export PATH=spack/bin:$PATH
$ spack install libelf
In general, most of your interactions with Spack will be through the
``spack`` command.
Install
--------------------
You don't need to install Spack; it's ready to run as soon as you
clone it from git.
You may want to run it out of a prefix other than the git repository
you cloned. The ``spack bootstrap`` command provides this
functionality. To install spack in a new directory, simply type:
.. code-block:: sh
$ spack bootstrap /my/favorite/prefix
This will install a new spack script in /my/favorite/prefix/bin, which
you can use just like you would the regular spack script. Each copy
of spack installs packages into its own ``$PREFIX/opt`` directory.
