Motivation
----------

Libraries should have as few dependencies as possible. `Tar` only
depends on Foundation because of a convenience wrapper function which
can easily be handled in the caller.

Modifications
-------------

* Remove the `public func tar(_ data: Data, filename: String) throws ->
[UInt8]` wrapper

Result
------

No functional change to `containertool`. `Tar` no longer depends on
Foundation.

Test Plan
---------

Existing tests continue to pass.

Motivation
----------

End to end and integration tests are failing because the underlying
Swift CI runner has been updated to use Swift 6.1 but these tests
install the 6.0.2 release of the Static Linux SDK.

Modifications
-------------

Update end to end and integration workflows to install the the 6.1
release of the Static Linux SDK.

Result
------

All tests will pass again.

Test Plan
---------

All existing tests pass again.

Motivation
----------

Tests scripts are used by GitHub Actions and when running tests locally.
They should have consistent structures, clean up after themselves and
print useful messages so that failures can be diagnosed.

Modifications
-------------

* Update all test scripts to use the same structure and cleanup options
as `run-integration-tests.sh`
* Add better diagnostic messages

Result
------

Test failures will be easier to diagnose

Test Plan
---------

Existing tests continue to pass.

…ages (#78)

Motivation
----------

A target in `Package.swift` can include
[resources](https://developer.apple.com/documentation/packagedescription/target/resources).
When the target is built, the resources are copied into a bundle
directory and a
[`Bundle`](https://developer.apple.com/documentation/foundation/bundle)
class is generated, giving the executable a convenient way to retrieve
them at run time.

A target with resources should be able to access them when it is
packaged in a container image. For example, a web server might bundle
resources such as images or fonts.

Fixes #48 

Modifications
-------------

* Add a new `--resource` parameter to `containertool`. This specifies a
resource bundle directory which is added to the container image using
the directory archiving support added to the `Tar` module in #74. When
`containertool` is used alone, multiple `--resource` flags can be
specified and will be added to the image in the order in which they
appear on the command line. A target in `Package.swift` can only define
one resource bundle, so when used through the plugin only one bundle
will be added.
* Update the plugin to pass the `--resource` flag to `containertool`
when an executable target has resources.

Result
------

If a target includes resources, the resource bundle will be copied into
the container image at a path where the generated `Bundle` class can
find it.
If a target does not include resources, the container image will only
include the executable.

Test Plan
---------

* Existing tests continue to pass.
* New integration tests verify that all expected resources are present.
