pyproject.toml:
Extend tool.poetry.scripts table to add an entrypoint for
`arch-release-sync`.

arch_release_promotion/cli.py:
Add `arch_release_sync()` as entrypoint for arch-release-sync, using
`files.ProjectFiles.sync()` to synchronize any configured releases for a
given project.

arch_release_promotion/files.py:
Add `load_release_from_json_payload()` to read a JSON payload and return
it as a Release instance.
Add the `ProjectFiles` class to aid in the synchronization of promoted
release types of a project by bundling all necessary functionality.
The special factory method `ProjectFiles.sync()` allows the creation of
a `ProjectFiles` instance and direct synchronization of the configured
amount of release versions of the project.

tests/test_files.py:
Add tests for `load_release_from_json_payload()`.
Add tests for `ProjectFiles` and all of its classmethods and instance
methods.

arch_release_promotion/gitlab.py:
Change `Upstream.download_release()` to also print the name of the
project.

arch_release_promotion/gitlab.py:
Add `download_promotion_artifact()` to allow download of a project
release's promotion artifact to a directory.

tests/test_gitlab.py:
Add tests for `download_promotion_artifact()`.

arch_release_promotion/argparse.py:
Add `ArgParseFactory.synchronize()` classmethod to add a simple
entrypoint for `arch-release-sync`, that supports the `-p`/`--project`
optional parameters and display of version information.

tests/test_argparse.py:
Add tests for `ArgParseFactory.synchronize()`.

arch_release_promotion/gitlab.py:
Change the `Upstream` constructor to accept private_token to be an
optional string.

arch_release_promotion/gitlab.py:
Add `Upstream.get_releases()` to allow retrieval of promoted or
unpromoted releases of an arbitrary upper limit.
Change `Upstream.select_release()` to use `Upstream.get_releases()`.

tests/test_gitlab.py:
Add parametrized test for `Upstream.get_releases()`.

arch_release_promotion/config.py:
Change `Settings.PRIVATE_TOKEN` to become an optional attribute, as it
is not required for readonly scenarios.
Order all `Settings` attributes alphabetically and add documentation for
them and their respective default values.
Change `Settings.validate_private_token()` to reflect the change in type
for `Settings.PRIVATE_TOKEN`.

tests/test_config.py:
Extend tests to also check for cases where `Settings.PRIVATE_TOKEN` is
None.

arch_release_promotion/config.py:
Add a `SyncConfig` pydantic model to track a global or per project
`backlog` (amount of versions synced), `directory` (with which to
synchronize), `last_updated_file` (to which to write a timestamp upon
changes in the synchronization directory) and `temp_in_sync_dir` (a bool
to set whether temporary data is downloaded to the synchronization
directory).
Add an optional instance of SyncConfig to both `ProjectConfig` and
`Projects`.
Add a root_validator to `Projects` to allow overriding the `SyncConfig`
of each project with implicit or global defaults if no `SyncConfig` is
provided.
Add validator for `Projects.projects` to ensure, that all
`ReleaseConfig` names of each `ProjectConfig` instances are unique.

tests/test_config.py:
Extend tests for `Projects` in accordance with changes to models.

* nl6720/gpg-options:
  signature.py: enforce sane gpg options

* Add --batch since gpg is not run manually.
* Add --no-armor to ensure that a .sig file is created instead of .asc in case gpg.conf sets the armor option.
* Add --no-include-key-block to skip including the public key in the signature and force the user who verifies the signature to acquire the public key from elsewhere.

Fixes #15.

* origin/issues/14:
  Increase project version to 0.1.1

  README: Point to example configuration
  Add an example file for projects configuration
  README: Change openmetrics section into configuration subsection
  README: Move "Use" section below "Requirements" section
  README: Update JSON payload section
  README: Fix typo in Configuration section
  README: Add section about promotion artifact
  Fix releng example configuration

README.rst:
Point to the example.toml for documentation purposes.

examples/example.toml:
Add a generic example file for project configuration that explains all
options.

README.rst:
As the openmetrics section is about how to configure openmetrics and
projects.toml to retrieve data from a build, it is best kept as a
subsection of the configuration section.

README.rst:
Move the "Use" section below "Requirements" section, as it was located
between sections that are dealing with configuration.

README.rst:
Update the JSON payload section to reflect the current settings around
metrics and how they are reflected in a JSON payload and update all
respective documentation around the payload's attributes.
Change the JSON payload section to become a subsection of the "Promotion
artifact" section.

README.rst:
Fix a typo in the Configuration section explaining that some of the
configuration options can also be passed in as environment variables.

README.rst:
Add section that explains the common files in a promotion artifact.

examples/projects.toml:
Change the releng example configuration to use all relevant metrics,
created by the releng releases and to create detached signatures for
relevant files per release type.

* origin/issues/4:
  gitlab-ci: Publish to pypi.org on tag

.gitlab-ci.yml:
Add a publish stage, that uses `poetry publish` on a secure runner to
push a release to pypi.org upon tagging. For this we make use of an
access token configured for the project via the environment variable
`POETRY_PYPI_TOKEN_PYPI`.

* origin/issues/5:
  cli: Change default program behavior to iterate over all projects
  argparse: Extend to show version and making project optional
  gitlab: Be explicit during release selection
  Remove hardcoded version string
  config: Raise when there are no project configurations

arch_release_promotion/cli.py:
Add `promote_project_release()` to promote releases of projects
generically. If no `release_version` is provided, user input is
requested to select a release that is not yet promoted.
Change `main()` to rely on `promote_project_release()` by either
promoting a specific release of a project (if the project or the project
and the release version are provided) or iterating over all available
projects in the configuration to allow the user to promote releases for
them.

arch_release_promotion/argparse.py:
Change `ArgParseFactory.__init__()` to allow overriding the program name
add a `-V`/`--version` argument which may be used to trigger showing the
version of the program.
Change `ArgParseFactory.promote()` to replace the required `name`
argument with the optional `-p`/`--project` argument and adding an
optional `-r`/`--release` argument which may be used to override the
release version to promote. Print program name and version information
and exit early if version information is requested.

tests/test_argparse.py:
Change tests to accomodate for the new optional arguments.

arch_release_promotion/cli.py:
Replace the use of `args.name` with `args.project`.

arch_release_promotion/gitlab.py:
Change `Upstream.select_release()` to also show the name of the project
for which the selection of the release is done.

arch_release_promotion/__init__.py:
Remove the hardcoded `__version__` string.
We want to rely on importlib metadata in the future.

arch_release_promotion/config.py:
Raise RuntimeError if there are no configuration files to be read.

tests/test_config.py:
Adapt tests for the case where there are no configuration files
supplied.

* issues/11:
  Add documentation on openmetrics
  examples: Change according to new metrics behavior
  Read openmetrics of different types

README.rst:

collect version, size, or amount information from a metrics file.
Change the JSON payload according to the more diverse set of understood
openmetrics.

examples/projects.toml:
Change the example configuration to make use of `version_metrics`
instead of `info_metrics`.
