* This fixes a number of bugs:
* Patches were not properly downloaded and added to mirrors.
* Mirror create didn't respect `list_url` in packages
* Update the `spack mirror` command to add all packages in the
concretized DAG (where originally it only added the package specified
by the user). This is required in order to collect patches that are specified
by dependents. Example:
* if X->Y and X requires a patch on Y called Pxy, then Pxy will only
be discovered if you create a mirror with X.
* replace confusing --one-version-per-spec option for `spack mirror create`
with --versions-per-spec; support retrieving multiple versions for
concrete specs
* Implementation details:
* `spack mirror create` now uses regular staging logic to download files
into a mirror, instead of reimplementing it in `add_single_spec`.
* use a separate resource caching object to keep track of new
resources and already-existing resources; also accepts storing
resources retrieved from a cache (unlike the local cache)
* mirror cache object now stores resources that are considered
non-cachable, like (e.g. the tip of a branch);
* the 'create' function of the mirror module no longer traverses
dependencies since this was already handled by the 'mirror' command;
* Change handling of `--no-checksum`:
* now that 'mirror create' uses stages, the mirror tests disable
checksums when creating the mirror
* remove `no_checksum` argument from library functions - this is now
handled at the Spack-command-level (like for 'spack install')

Spack
Spack is a multi-platform package manager that builds and installs multiple versions and configurations of software. It works on Linux, macOS, and many supercomputers. Spack is non-destructive: installing a new version of a package does not break existing installations, so many configurations of the same package can coexist.
Spack offers a simple "spec" syntax that allows users to specify versions and configuration options. Package files are written in pure Python, and specs allow package authors to write a single script for many different builds of the same package. With Spack, you can build your software all the ways you want to.
See the Feature Overview for examples and highlights.
To install spack and your first package, make sure you have Python. Then:
$ git clone https://github.com/spack/spack.git
$ cd spack/bin
$ ./spack install libelf
