+podman - for running OCI-based containers in Pods
+
+libpod provides a library for applications looking to use the Container Pod
+concept popularized by Kubernetes. libpod also contains a tool called podman
+for managing Pods, Containers, and Container Images.
+
+At a high level, the scope of libpod and podman is the following:
+* Support multiple image formats including the existing Docker/OCI image formats.
+* Support for multiple means to download images including trust & image verification.
+* Container image management (managing image layers, overlay filesystems, etc).
+* Full management of container lifecycle
+* Support for pods to manage groups of containers together
+* Resource isolation of containers and pods.
+
+These container runtimes can run as non-root, but require sub-uid/gid mappings

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
