Top-like interface for container metrics

`ctop` provides a concise and condensed overview of real-time metrics for multiple containers:
<p align="center"><img src="_docs/img/grid.gif" alt="ctop"/></p>

as well as a [single container view][single_view] for inspecting a specific container.

`ctop` comes with built-in support for Docker and runC; connectors for other container and cluster systems are planned for future releases.

## Building

Build steps can be found [here][build].

## Usage

`ctop` requires no arguments and uses Docker host variables by default. See [connectors][connectors] for further configuration options.

### Config file

While running, use `S` to save the current filters, sort field, and other options to a default config path (`~/.config/ctop/config` on XDG systems, else `~/.ctop`).

Config file values will be loaded and applied the next time `ctop` is started.

### Options

Option | Description
--- | ---
`-a`	| show active containers only
`-f <string>` | set an initial filter string
`-h`	| display help dialog
`-i`  | invert default colors
`-r`	| reverse container sort order
`-s`  | select initial container sort field
`-scale-cpu`	| show cpu as % of system total
`-v`	| output version information and exit
`-shell` | exec shell to use (default: sh)
