+SUMMARY = "Linux container runtime"
+DESCRIPTION = "Linux container runtime \
+ Docker complements kernel namespacing with a high-level API which \
+ operates at the process level. It runs unix processes with strong \
+ guarantees of isolation and repeatability across servers. \
+ . \
+ Docker is a great building block for automating distributed systems: \
+ large-scale web deployments, database clusters, continuous deployment \
+ systems, private PaaS, service-oriented architectures, etc. \
+ . \
+ This package contains the daemon and client. Using docker.io on non-amd64 \
+ hosts is not supported at this time. Please be careful when using it \
+ on anything besides amd64. \
+ . \
+ Also, note that kernel version 3.8 or above is required for proper \
+ operation of the daemon process, and that any lower versions may have \
+ subtle and/or glaring issues. \

+# Reason:
+# The "docker" package contains two binaries: "docker" and "dockerinit",
+# which are both written in Go. The "dockerinit" package is built first,
+# then its checksum is given to the build process compiling the "docker"
+# binary. Hence the checksum of the unstripped "dockerinit" binary is hard
+# coded into the "docker" binary. At runtime the "docker" binary invokes
+# the "dockerinit" binary, but before doing that it ensures the checksum
+# of "dockerinit" matches with the hard coded value.
