#   - package implicitly provides
#     `${package_name}${ABI_version}=${package_version}`
#     this implies that only one version of a package per ABI can be installed
#     at the same time
#   - additionally provide `${package_name}` so multiple packages can be looked
#     up by its base name
#   - for each `provides`:
#     - provide `${provide}${ABI_version}=${package_version}`
#       this implies that only one version of a provide can be installed at the
#       same time
#     - if a `provide` ends in a number, the `ABI_version` will be prefixed with
#       a - sign, e.g.: provide1-0
#     - additionally provide `${provide}` so multiple packages can be looked up
#       by its base name
#
# - else if ABI version is _not_ defined
#   - package is named `${package_name}`
#   - package implicitly provides `${package_name}=${package_version}`
#     this implies that only one version of a package can be installed at the
#     same time
#   - for each `provides`, provide `${provide}=${package_version}` this implies
#     that only one version of a provide can be installed at the same time
#
# - Both with and without an ABI, if a provide starts with an @, treat it as a
#   virtual provide, that doesn't own the name by not appending version.
#   Multiple packages with the same virtual provides can be installed
#   side-by-side.
#
# - apk doesn't like it when packages specify a redundant provide pointing to
#   self. Filter it out, but keep virtual self provides, in the form of
#   @(kmod-)?${package_name}-any.
#
# - Packages implicitly add a virtual @${package_name}-any provide in Package,
#   which implies that kmods, which are also packages, will have a virtual
#   @kmod-${package_name}-any provide.
#
# - Aside from the two aforementioned implicit provides, packages are expected
#   to manage their provides themselves.
#
# - When multiple variants inside the same package have the same provide, a
#   default variant must be set using DEFAULT_VARIANT:=1.
#
# - Cross-package provides must be virtual and a default variant must be set. If
#   different packages provide the same versioned (i.e. non-virtual) provide the
#   package with a higher version will be preferred, which results in unintended
#   behavior, because the order might change with package updates.
#
#   Example:
#   - both uclient-fetch and wget provide wget
#   - wget doesn't have a default variant called wget that would provide an
#     implicit @wget-any
#     - add wget to PROVIDES for both wget-ssl and wget-nossl variants so they
#       can't be installed at the same time
#     - add @wget-any to both packages so packages outside of wget can provide
#       it
#   - uclient-fetch has only one variant
#     - add @wget-any to PROVIDES
#     - mark uclient-fetch as the default variant using DEFAULT_VARIANT:=1
#   - switch wget consumer that don't depend on a specific version like apk to
#     depend on @wget-any
#
# - Alternatives don't affect the packaging.
