# buzzec-strip-dag-node
This command line application strips nodes from a given DAG. The dag is given in the format of `[x-y],*` where `x` and `y` are any utf-8 strings without whitespace, `-`, or `,`.

If no strip flag is added then the command will remove duplicate edges, verify the DAG, and alphabetize.
### Strip behavior
When a node is removed, all it's children are added to all it's parents.

## Help output:
```
buzzec-strip-dag-node 0.1.0
Strips out a dag node. Defaults to stdin, use --in to input a command line argument. If skip and no-verify are not
present will verify and format the given DAG.
