-   old default), you can use `spack install --fresh`, or add
-   configuration like this to your environment or `concretizer.yaml`:
-
-   ```yaml
-   concretizer:
-       reuse: false
-   ```
-
-2. **Finer-grained hashes**
-
-   Spack hashes now include `link`, `run`, *and* `build` dependencies,
-   as well as a canonical hash of package recipes. Previously, hashes
-   only included `link` and `run` dependencies (though `build`
-   dependencies were stored by environments). We coarsened the hash to
-   reduce churn in user installations, but the new default concretizer
-   behavior mitigates this concern and gets us reuse *and* provenance.
-   You will be able to see the build dependencies of new installations
-   with `spack find`. Old installations will not change and their
-   hashes will not be affected. (#28156, #28504, #30717, #30861)
-
-3. **Improved error messages**
-
-   Error handling with the new concretizer is now done with
-   optimization criteria rather than with unsatisfiable cores, and
-   Spack reports many more details about conflicting constraints.
-   (#30669)
-
-4. **Unify environments when possible**
-
-   Environments have thus far supported `concretization: together` or
-   `concretization: separately`. These have been replaced by a new
-   preference in `concretizer.yaml`:
-
-   ```yaml
-   concretizer:
-       unify: [true|false|when_possible]
-   ```
-
-   `concretizer:unify:when_possible` will *try* to resolve a fully
-   unified environment, but if it cannot, it will create multiple
-   configurations of some packages where it has to. For large
-   environments that previously had to be concretized separately, this
-   can result in a huge speedup (40-50x). (#28941)
-
-5. **Automatically find externals on Cray machines**
-
-   Spack can now automatically discover installed packages in the Cray
-   Programming Environment by running `spack external find` (or `spack
-   external read-cray-manifest` to *only* query the PE). Packages from
-   the PE (e.g., `cray-mpich` are added to the database with full
-   dependency information, and compilers from the PE are added to
-   `compilers.yaml`. Available with the June 2022 release of the Cray
-   Programming Environment. (#24894, #30428)
-
-6. **New binary format and hardened signing**
-
-   Spack now has an updated binary format, with improvements for
-   security. The new format has a detached signature file, and Spack
-   verifies the signature before untarring or decompressing the binary
-   package. The previous format embedded the signature in a `tar`
-   file, which required the client to run `tar` *before* verifying
-   (#30750). Spack can still install from build caches using the old
-   format, but we encourage users to switch to the new format going
-   forward.
-
-   Production GitLab pipelines have been hardened to securely sign
-   binaries. There is now a separate signing stage so that signing
-   keys are never exposed to build system code, and signing keys are
-   ephemeral and only live as long as the signing pipeline stage.
-   (#30753)
-
-7. **Bootstrap mirror generation**
-
-   The `spack bootstrap mirror` command can automatically create a
-   mirror for bootstrapping the concretizer and other needed
-   dependencies in an air-gapped environment. (#28556)
-
-8. **Nascent Windows support**
-
-   Spack now has initial support for Windows. Spack core has been
-   refactored to run in the Windows environment, and a small number of
-   packages can now build for Windows. More details are
-   [in the documentation](https://spack.rtfd.io/en/latest/getting_started.html#spack-on-windows)
-   (#27021, #28385, many more)
-
-9. **Makefile generation**
-
-   `spack env depfile` can be used to generate a `Makefile` from an
-   environment, which can be used to build packages the environment
-   in parallel on a single node. e.g.:
-
-   ```console
-   spack -e myenv env depfile > Makefile
-   make
-   ```
-
-   Spack propagates `gmake` jobserver information to builds so that
-   their jobs can share cores. (#30039, #30254, #30302, #30526)
-
-10. **New variant features**
-
-    In addition to being conditional themselves, variants can now have
-    [conditional *values*](https://spack.readthedocs.io/en/latest/packaging_guide.html#conditional-possible-values)
-    that are only possible for certain configurations of a package. (#29530)
-
-    Variants can be
-    [declared "sticky"](https://spack.readthedocs.io/en/latest/packaging_guide.html#sticky-variants),
-    which prevents them from being enabled or disabled by the
-    concretizer. Sticky variants must be set explicitly by users
-    on the command line or in `packages.yaml`. (#28630)
-
-* Allow conditional possible values in variants
-* Add a "sticky" property to variants
-
-
-## Other new features of note
-
-* Environment views can optionally link only `run` dependencies
-  with `link:run` (#29336)
-* `spack external find --all` finds library-only packages in
-  addition to build dependencies (#28005)
-* Customizable `config:license_dir` option (#30135)
-* `spack external find --path PATH` takes a custom search path (#30479)
-* `spack spec` has a new `--format` argument like `spack find` (#27908)
-* `spack concretize --quiet` skips printing concretized specs (#30272)
-* `spack info` now has cleaner output and displays test info (#22097)
-* Package-level submodule option for git commit versions (#30085, #30037)
-* Using `/hash` syntax to refer to concrete specs in an environment
-  now works even if `/hash` is not installed. (#30276)
-
-## Major internal refactors
-
-* full hash (see above)
-* new develop versioning scheme `0.19.0-dev0`
-* Allow for multiple dependencies/dependents from the same package (#28673)
-* Splice differing virtual packages (#27919)
-
-## Performance Improvements
-
-* Concretization of large environments with `unify: when_possible` is
-  much faster than concretizing separately (#28941, see above)
-* Single-pass view generation algorithm is 2.6x faster (#29443)
-
-## Archspec improvements
-
-* `oneapi` and `dpcpp` flag support (#30783)
-* better support for `M1` and `a64fx` (#30683)
-
-## Removals and Deprecations
-
-* Spack no longer supports Python `2.6` (#27256)
-* Removed deprecated `--run-tests` option of `spack install`;
-  use `spack test` (#30461)
-* Removed deprecated `spack flake8`; use `spack style` (#27290)
-
-* Deprecate `spack:concretization` config option; use
-  `concretizer:unify` (#30038)
-* Deprecate top-level module configuration; use module sets (#28659)
-* `spack activate` and `spack deactivate` are deprecated in favor of
-  environments; will be removed in `0.19.0` (#29430; see also `link:run`
-  in #29336 above)
-
-## Notable Bugfixes
-
-* Fix bug that broke locks with many parallel builds (#27846)
-* Many bugfixes and consistency improvements for the new concretizer
-  and `--reuse` (#30357, #30092, #29835, #29933, #28605, #29694, #28848)
-
-## Packages
-
-* `CMakePackage` uses `CMAKE_INSTALL_RPATH_USE_LINK_PATH` (#29703)
-* Refactored `lua` support: `lua-lang` virtual supports both
-  `lua` and `luajit` via new `LuaPackage` build system(#28854)
-* PythonPackage: now installs packages with `pip` (#27798)
-* Python: improve site_packages_dir handling (#28346)
-* Extends: support spec, not just package name (#27754)
-* `find_libraries`: search for both .so and .dylib on macOS (#28924)
-* Use stable URLs and `?full_index=1` for all github patches (#29239)

-
-=============
-Bootstrapping
-=============
-
-In the :ref:`Getting started <getting_started>` Section we already mentioned that
-Spack can bootstrap some of its dependencies, including ``clingo``. In fact, there
-is an entire command dedicated to the management of every aspect of bootstrapping:
-
-.. command-output:: spack bootstrap --help
-
-The first thing to know to understand bootstrapping in Spack is that each of
-Spack's dependencies is bootstrapped lazily; i.e. the first time it is needed and
-can't be found. You can readily check if any prerequisite for using Spack
-is missing by running:
-
-.. code-block:: console
-
-   % spack bootstrap status
-   Spack v0.17.1 - python@3.8
-
-   [FAIL] Core Functionalities
-     [B] MISSING "clingo": required to concretize specs
-
-   [FAIL] Binary packages
-     [B] MISSING "gpg2": required to sign/verify buildcaches
-
-
-   Spack will take care of bootstrapping any missing dependency marked as [B]. Dependencies marked as [-] are instead required to be found on the system.
-
-In the case of the output shown above Spack detected that both ``clingo`` and ``gnupg``
-are missing and it's giving detailed information on why they are needed and whether
-they can be bootstrapped. Running a command that concretize a spec, like:
-
-.. code-block:: console
-
-   % spack solve zlib
-   ==> Bootstrapping clingo from pre-built binaries
-   ==> Fetching https://mirror.spack.io/bootstrap/github-actions/v0.1/build_cache/darwin-catalina-x86_64/apple-clang-12.0.0/clingo-bootstrap-spack/darwin-catalina-x86_64-apple-clang-12.0.0-clingo-bootstrap-spack-p5on7i4hejl775ezndzfdkhvwra3hatn.spack
-   ==> Installing "clingo-bootstrap@spack%apple-clang@12.0.0~docs~ipo+python build_type=Release arch=darwin-catalina-x86_64" from a buildcache
-   [ ... ]
-
-triggers the bootstrapping of clingo from pre-built binaries as expected.
-
------------------------
-The Bootstrapping store
------------------------
-
-The software installed for bootstrapping purposes is deployed in a separate store.
-Its location can be checked with the following command:
-
-.. code-block:: console
-
-   % spack bootstrap root
-
-It can also be changed with the same command by just specifying the newly desired path:
-
-.. code-block:: console
-
-   % spack bootstrap root /opt/spack/bootstrap
-
-You can check what is installed in the bootstrapping store at any time using:
-
-.. code-block:: console
-
-   % spack find -b
-   ==> Showing internal bootstrap store at "/Users/spack/.spack/bootstrap/store"
-   ==> 11 installed packages
-   -- darwin-catalina-x86_64 / apple-clang@12.0.0 ------------------

-   gnupg@2.3.1             libgcrypt@1.9.3  libiconv@1.16      npth@1.6       python@3.8
-
-In case it is needed you can remove all the software in the current bootstrapping store with:
-
-.. code-block:: console
-
-   % spack clean -b
-   ==> Removing bootstrapped software and configuration in "/Users/spack/.spack/bootstrap"
-
-   % spack find -b
-   ==> Showing internal bootstrap store at "/Users/spack/.spack/bootstrap/store"
-   ==> 0 installed packages
-
---------------------------------------------
-Enabling and disabling bootstrapping methods
---------------------------------------------
-
-Bootstrapping is always performed by trying the methods listed by:
-
-.. command-output:: spack bootstrap list
-
-in the order they appear, from top to bottom. By default Spack is
-configured to try first bootstrapping from pre-built binaries and to
-fall-back to bootstrapping from sources if that failed.
-
-If need be, you can disable bootstrapping altogether by running:
-
-.. code-block:: console
-
-   % spack bootstrap disable
-
-in which case it's your responsibility to ensure Spack runs in an
-environment where all its prerequisites are installed. You can
-also configure Spack to skip certain bootstrapping methods by *untrusting*
-them. For instance:
-
-.. code-block:: console
-
-   % spack bootstrap untrust github-actions
-   ==> "github-actions" is now untrusted and will not be used for bootstrapping
-
-tells Spack to skip trying to bootstrap from binaries. To add the "github-actions" method back you can:
-
-.. code-block:: console
-
-   % spack bootstrap trust github-actions
-
-There is also an option to reset the bootstrapping configuration to Spack's defaults:
-
-.. code-block:: console
-
-   % spack bootstrap reset
-   ==> Bootstrapping configuration is being reset to Spack's defaults. Current configuration will be lost.
-   Do you want to continue? [Y/n]
-   %
-
-----------------------------------------
-Creating a mirror for air-gapped systems
-----------------------------------------
-
-Spack's default configuration for bootstrapping relies on the user having
-access to the internet, either to fetch pre-compiled binaries or source tarballs.
-Sometimes though Spack is deployed on air-gapped systems where such access is denied.
-
-To help with similar situations Spack has a command that recreates, in a local folder
-of choice, a mirror containing the source tarballs and/or binary packages needed for
-bootstrapping.
-
-.. code-block:: console
-
-   % spack bootstrap mirror --binary-packages /opt/bootstrap
-   ==> Adding "clingo-bootstrap@spack+python %apple-clang target=x86_64" and dependencies to the mirror at /opt/bootstrap/local-mirror
-   ==> Adding "gnupg@2.3: %apple-clang target=x86_64" and dependencies to the mirror at /opt/bootstrap/local-mirror
-   ==> Adding "patchelf@0.13.1:0.13.99 %apple-clang target=x86_64" and dependencies to the mirror at /opt/bootstrap/local-mirror
-   ==> Adding binary packages from "https://github.com/alalazo/spack-bootstrap-mirrors/releases/download/v0.1-rc.2/bootstrap-buildcache.tar.gz" to the mirror at /opt/bootstrap/local-mirror
-
-   To register the mirror on the platform where it's supposed to be used run the following command(s):
-     % spack bootstrap add --trust local-sources /opt/bootstrap/metadata/sources
-     % spack bootstrap add --trust local-binaries /opt/bootstrap/metadata/binaries
-
-
-This command needs to be run on a machine with internet access and the resulting folder
-has to be moved over to the air-gapped system. Once the local sources are added using the
-commands suggested at the prompt, they can be used to bootstrap Spack.

-------------------
-CachedCMakePackage
-------------------
-
-The CachedCMakePackage base class is used for CMake-based workflows
-that create a CMake cache file prior to running ``cmake``. This is
-useful for packages with arguments longer than the system limit, and
-for reproducibility.
-
-The documentation for this class assumes that the user is familiar with
-the ``CMakePackage`` class from which it inherits. See the documentation
-for :ref:`CMakePackage <cmakepackage>`.
-
-^^^^^^
-Phases
-^^^^^^
-
-The ``CachedCMakePackage`` base class comes with the following phases:
-
-#. ``initconfig`` - generate the CMake cache file
-#. ``cmake`` - generate the Makefile
-#. ``build`` - build the package
-#. ``install`` - install the package
-
-By default, these phases run:
-
-.. code-block:: console
-
-   $ mkdir spack-build
-   $ cd spack-build
-   $ cat << EOF > name-arch-compiler@version.cmake
-   # Write information on compilers and dependencies
-   # includes information on mpi and cuda if applicable
-   $ cmake .. -DCMAKE_INSTALL_PREFIX=/path/to/installation/prefix -C name-arch-compiler@version.cmake
-   $ make
-   $ make test  # optional
-   $ make install
-
-The ``CachedCMakePackage`` class inherits from the ``CMakePackage``
-class, and accepts all of the same options and adds all of the same
-flags to the ``cmake`` command. Similar to the ``CMakePAckage`` class,
-you may need to add a few arguments yourself, and the
-``CachedCMakePackage`` provides the same interface to add those
-flags.
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Adding entries to the CMake cache
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-In addition to adding flags to the ``cmake`` command, you may need to
-add entries to the CMake cache in the ``initconfig`` phase. This can
-be done by overriding one of four methods:
-
-#. ``CachedCMakePackage.initconfig_compiler_entries``
-#. ``CachedCMakePackage.initconfig_mpi_entries``
-#. ``CachedCMakePackage.initconfig_hardware_entries``
-#. ``CachedCMakePackage.initconfig_package_entries``
-
-Each of these methods returns a list of CMake cache strings. The
-distinction between these methods is merely to provide a
-well-structured and legible cmake cache file -- otherwise, entries
-from each of these methods are handled identically.
-
-Spack also provides convenience methods for generating CMake cache
-entries. These methods are available at module scope in every Spack
-package. Because CMake parses boolean options, strings, and paths
-differently, there are three such methods:
-
-#. ``cmake_cache_option``
-#. ``cmake_cache_string``
-#. ``cmake_cache_path``
-
-These methods each accept three parameters -- the name of the CMake
-variable associated with the entry, the value of the entry, and an
-optional comment -- and return strings in the appropriate format to be
-returned from any of the ``initconfig*`` methods. Additionally, these
-methods may return comments beginning with the ``#`` character.
-
-A typical usage of these methods may look something like this:
-
-.. code-block:: python
-
-   def initconfig_mpi_entries(self)
-       # Get existing MPI configurations
-       entries = super(self, Foo).initconfig_mpi_entries()
-
-       # The existing MPI configurations key on whether ``mpi`` is in the spec
-       # This spec has an MPI variant, and we need to enable MPI when it is on.
-       # This hypothetical package controls MPI with the ``FOO_MPI`` option to
-       # cmake.
-       if '+mpi' in self.spec:
-           entries.append(cmake_cache_option('FOO_MPI', True, "enable mpi"))
-       else:
-           entries.append(cmake_cache_option('FOO_MPI', False, "disable mpi"))
-
-   def initconfig_package_entries(self):
-       # Package specific options
-       entries = []
-
-       entries.append('#Entries for build options')
-
-       bar_on = '+bar' in self.spec
-       entries.append(cmake_cache_option('FOO_BAR', bar_on, 'toggle bar'))
-
-       entries.append('#Entries for dependencies')
-
-       if self.spec['blas'].name == 'baz':  # baz is our blas provider
-       entries.append(cmake_cache_string('FOO_BLAS', 'baz', 'Use baz'))
-       entries.append(cmake_cache_path('BAZ_PREFIX', self.spec['baz'].prefix))

+
+-----------------
+Writing analyzers
+-----------------
+
+To write an analyzer, you should add a new python file to the
+analyzers module directory at ``lib/spack/spack/analyzers`` .
+Your analyzer should be a subclass of the :class:`AnalyzerBase <spack.analyzers.analyzer_base.AnalyzerBase>`. For example, if you want
+to add an analyzer class ``Myanalyzer`` you would write to
+``spack/analyzers/myanalyzer.py`` and import and
+use the base as follows:
+
+.. code-block:: python
+
+    from .analyzer_base import AnalyzerBase
+
+    class Myanalyzer(AnalyzerBase):
+
+
+Note that the class name is your module file name, all lowercase
+except for the first capital letter. You can  look at other analyzers in
+that analyzer directory for examples. The guide here will tell you about the basic functions needed.
+
+^^^^^^^^^^^^^^^^^^^^^^^^^
+Analyzer Output Directory
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+By default, when you run ``spack analyze run`` an analyzer output directory will
+be created in your spack user directory in your ``$HOME``. The reason we output here
+is because the install directory might not always be writable.
+
+.. code-block:: console
+
+    ~/.spack/
+      analyzers
+
+Result files will be written here, organized in subfolders in the same structure
+as the package, with each analyzer owning it's own subfolder. for example:
+
+
+.. code-block:: console
+
+    $ tree ~/.spack/analyzers/
+    /home/spackuser/.spack/analyzers/
+    └── linux-ubuntu20.04-skylake
+        └── gcc-9.3.0
+            └── zlib-1.2.11-sl7m27mzkbejtkrajigj3a3m37ygv4u2
+                ├── environment_variables
+                │   └── spack-analyzer-environment-variables.json
+                ├── install_files
+                │   └── spack-analyzer-install-files.json
+                └── libabigail
+                    └── lib
+                        └── spack-analyzer-libabigail-libz.so.1.2.11.xml
+
+
+Notice that for the libabigail analyzer, since results are generated per object,
+we honor the object's folder in case there are equivalently named files in
+different folders. The result files are typically written as json so they can be easily read and  uploaded in a future interaction with a monitor.
+
+
+^^^^^^^^^^^^^^^^^
+Analyzer Metadata
+^^^^^^^^^^^^^^^^^
+
+Your analyzer is required to have the class attributes ``name``, ``outfile``,
+and ``description``. These are printed to the user with they use the subcommand
+``spack analyze list-analyzers``.  Here is an example.
+As we mentioned above, note that this analyzer would live in a module named
+``libabigail.py`` in the analyzers folder so that the class can be discovered.
+
+
+.. code-block:: python
+
+    class Libabigail(AnalyzerBase):
+
+        name = "libabigail"
+        outfile = "spack-analyzer-libabigail.json"
+        description = "Application Binary Interface (ABI) features for objects"
+
+
+This means that the name and output file should be unique for your analyzer.
+Note that "all" cannot be the name of an analyzer, as this key is used to indicate
+that the user wants to run all analyzers.
+
+.. _analyzer_run_function:
+
+
+^^^^^^^^^^^^^^^^^^^^^^^^
+An analyzer run Function
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+The core of an analyzer is its ``run()`` function, which should accept no
+arguments. You can assume your analyzer has the package spec of interest at ``self.spec``
+and it's up to the run function to generate whatever analysis data you need,
+and then return the object with a key as the analyzer name. The result data
+should be a list of objects, each with a name, ``analyzer_name``, ``install_file``,
+and one of ``value`` or ``binary_value``. The install file should be for a relative
+path, and not the absolute path. For example, let's say we extract a metric called
+``metric`` for ``bin/wget`` using our analyzer ``thebest-analyzer``.
+We might have data that looks like this:
+
+.. code-block:: python
+
+    result = {"name": "metric", "analyzer_name": "thebest-analyzer", "value": "1", "install_file": "bin/wget"}
+
+
+We'd then return it as follows - note that they key is the analyzer name at ``self.name``.
+
+.. code-block:: python
+
+    return {self.name: result}
+
+This will save the complete result to the analyzer metadata folder, as described
+previously. If you want support for adding a different kind of metadata (e.g.,
+not associated with an install file) then the monitor server would need to be updated
+to support this first.
+
+
+^^^^^^^^^^^^^^^^^^^^^^^^^
+An analyzer init Function
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If you don't need any extra dependencies or checks, you can skip defining an analyzer
+init function, as the base class will handle it. Typically, it will accept
+a spec, and an optional output directory (if the user does not want the default
+metadata folder for analyzer results). The analyzer init function should call
+it's parent init, and then do any extra checks or validation that are required to
+work. For example:
+
+.. code-block:: python
+
+    def __init__(self, spec, dirname=None):
+        super(Myanalyzer, self).__init__(spec, dirname)
+
+        # install extra dependencies, do extra preparation and checks here
+
+
+At the end of the init, you will have available to you:
+
+ - **self.spec**: the spec object
+ - **self.dirname**: an optional directory name the user as provided at init to save
+ - **self.output_dir**: the analyzer metadata directory, where we save by default
+ - **self.meta_dir**: the path to the package metadata directory (.spack) if you need it
+
+And can proceed to write your analyzer.
+
+
+^^^^^^^^^^^^^^^^^^^^^^^
+Saving Analyzer Results
+^^^^^^^^^^^^^^^^^^^^^^^
+
+The analyzer will have ``save_result`` called, with the result object generated
+to save it to the filesystem, and if the user has added the ``--monitor`` flag
+to upload it to a monitor server. If your result follows an accepted result
+format and you don't need to parse it further, you don't need to add this
+function to your class. However, if your result data is large or otherwise
+needs additional parsing, you can define it. If you define the function, it
+is useful to know about the ``output_dir`` property, which you can join
+with your output file relative path of choice:
+
+.. code-block:: python
+
+    outfile = os.path.join(self.output_dir, "my-output-file.txt")
+
+
+The directory will be provided by the ``output_dir`` property but it won't exist,
+so you should create it:
+
+
+.. code::block:: python
+
+    # Create the output directory
+    if not os.path.exists(self._output_dir):
+        os.makedirs(self._output_dir)
+
+
+If you are generating results that match to specific files in the package
+install directory, you should try to maintain those paths in the case that
+there are equivalently named files in different directories that would
+overwrite one another. As an example of an analyzer with a custom save,
+the Libabigail analyzer saves ``*.xml`` files to the analyzer metadata
+folder in ``run()``, as they are either binaries, or as xml (text) would
+usually be too big to pass in one request. For this reason, the files
+are saved during ``run()`` and the filenames added to the result object,
+and then when the result object is passed back into ``save_result()``,
+we skip saving to the filesystem, and instead read the file and send
+each one (separately) to the monitor:
+
+
+.. code-block:: python
+
+    def save_result(self, result, monitor=None, overwrite=False):
+        """ABI results are saved to individual files, so each one needs to be
+        read and uploaded. Result here should be the lookup generated in run(),
+        the key is the analyzer name, and each value is the result file.
+        We currently upload the entire xml as text because libabigail can't
+        easily read gzipped xml, but this will be updated when it can.
+        """
+        if not monitor:
+            return
+
+        name = self.spec.package.name
+
+        for obj, filename in result.get(self.name, {}).items():
+
+            # Don't include the prefix
+            rel_path = obj.replace(self.spec.prefix + os.path.sep, "")
+
+            # We've already saved the results to file during run
+            content = spack.monitor.read_file(filename)
+
+            # A result needs an analyzer, value or binary_value, and name
+            data = {"value": content, "install_file": rel_path, "name": "abidw-xml"}
+            tty.info("Sending result for %s %s to monitor." % (name, rel_path))
+            monitor.send_analyze_metadata(self.spec.package, {"libabigail": [data]})
+
+
+
+Notice that this function, if you define it, requires a result object (generated by
+``run()``, a monitor (if you want to send), and a boolean ``overwrite`` to be used
+to check if a result exists first, and not write to it if the result exists and
+overwrite is False. Also notice that since we already saved these files to the analyzer metadata folder, we return early if a monitor isn't defined, because this function serves to send  results to the monitor. If you haven't saved anything to the analyzer metadata folder
+yet, you might want to do that here. You should also use ``tty.info`` to give
+the user a message of "Writing result to $DIRNAME."

-Consider a package ``foo`` that can optionally provide two virtual
-packages ``bar`` and ``baz``.  When both are enabled the installation tree

-.. code-block:: console

-   lib64/libFoo.so
-   lib64/libFooBar.so
-   baz/include/baz/baz.h
-   baz/lib/libFooBaz.so
-
-The install tree shows that ``foo`` is providing the header ``include/foo.h``
-and library ``lib64/libFoo.so`` in it's install prefix.  The virtual
-package ``bar`` is providing ``include/bar/bar.h`` and library
-``lib64/libFooBar.so``, also in ``foo``'s install prefix.  The ``baz``
-package, however, is provided in the ``baz`` subdirectory of ``foo``'s
-prefix with the ``include/baz/baz.h`` header and ``lib/libFooBaz.so``
-library.  Such a package could implement the optional attributes as
-follows:
-

-   :linenos:
-
-   class Foo(Package):
