reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work

unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason

## areflect
Helper functions to work with the `reflect` package. Contains
`ForceExport()`, which bypasses the check in `reflect.Value` that
prevents accessing unexported attributes.
## monotime
Provides access to a fast monotonic clock source, to fill in the gap in the
[Go standard library, which lacks one](https://github.com/golang/go/issues/12914).
Don't use `time.Now()` in code that needs to time things or otherwise assume
that time passes at a constant rate, instead use `monotime.Now()`.
## cmd
See the [cmd](cmd) directory.
## dscp
Provides `ListenTCPWithTOS()`, which is a replacement for `net.ListenTCP()`
that allows specifying the ToS (Type of Service), to specify DSCP / ECN /
class of service flags to use for incoming connections.
## key
Provides a common type used across various Arista projects, named `key.Key`,
which is used to work around the fact that Go can't let one
use a non-hashable type as a key to a `map`, and we sometimes need to use
a `map[string]interface{}` (or something containing one) as a key to maps.
As a result, we frequently use `map[key.Key]interface{}` instead of just
`map[interface{}]interface{}` when we need a generic key-value collection.
## lanz
A client for [LANZ](https://eos.arista.com/latency-analyzer-lanz-architectures-and-configuration/)
streaming servers. It connects to a LANZ streaming server,
listens for notifications, decodes them and sends the LANZ protobuf on the
provided channel.
## monitor
A library to help expose monitoring metrics on top of the
[`expvar`](https://golang.org/pkg/expvar/) infrastructure.
## netns
`netns.Do(namespace, cb)` provides a handy mechanism to execute the given
callback `cb` in the given [network namespace](https://lwn.net/Articles/580893/).
## pathmap
A datastructure for mapping keys of type string slice to values. It
allows for some fuzzy matching.
## test
This is a [Go](http://golang.org/) library to help in writing unit tests.
## Examples
TBD
