+module: rhel_rpm_ostree
+version_added: 1.5.0
+short_description: Ensure packages exist in a RHEL for Edge rpm-ostree based system
+description:
+  - Compatibility layer for using the "package" module for RHEL for Edge systems utilizing the RHEL System Roles.
+author:
+  - Adam Miller (@maxamillion)
+requirements:
+  - rpm-ostree
+options:
+  name:
+    description:
+      - A package name or package specifier with version, like C(name-1.0).
+      - Comparison operators for package version are valid here C(>), C(<), C(>=), C(<=). Example - C(name>=1.0)
+      - If a previous version is specified, the task also needs to turn C(allow_downgrade) on.
+        See the C(allow_downgrade) documentation for caveats with downgrading packages.
+      - When using state=latest, this can be C('*') which means run C(yum -y update).
+      - You can also pass a url or a local path to a rpm file (using state=present).
+        To operate on several packages this can accept a comma separated string of packages or (as of 2.0) a list of packages.
+    aliases: [ pkg ]
+    type: list
+    elements: str
+  state:
+    description:
+      - Whether to install (C(present) or C(installed), C(latest)), or remove (C(absent) or C(removed)) a package.
+      - C(present) and C(installed) will simply ensure that a desired package is installed.
+      - C(latest) will update the specified package if it's not of the latest available version.
+      - C(absent) and C(removed) will remove the specified package.
+      - Default is C(None), however in effect the default action is C(present) unless the C(autoremove) option is
+        enabled for this module, then C(absent) is inferred.
+    type: str
+    choices: [ absent, installed, latest, present, removed ]
+notes:
+  - This module does not support installing or removing packages to/from an overlay as this is not supported
+    by RHEL for Edge, packages needed should be defined in the osbuild Blueprint and provided to Image Builder
+    at build time. This module exists only for C(package) module compatibility.
