reported to the community leaders responsible for enforcement at
.
All complaints will be reviewed and investigated promptly and fairly.

All community leaders are obligated to respect the privacy and security of the
reporter of any incident.

## Enforcement Guidelines

Community leaders will follow these Community Impact Guidelines in determining
the consequences for any action they deem in violation of this Code of Conduct:

### 1. Correction

 * Your account of what occurred, and if you believe the incident is ongoing. If there is a publicly
   available record (e.g. a mailing list archive or a public IRC logger), please include a link.
 * Any additional information that may be helpful.

After filing a report, a representative from the Square Code of Conduct committee will contact you
personally. The committee will then review the incident, follow up with any additional questions,

   * self-loops twice (equivalently, the number of times an edge touches {@code node}).
   *
   * <p>For directed networks, this is equal to {@code inDegree(node) + outDegree(node)}.
   *
   * <p>For undirected networks, this is equal to {@code incidentEdges(node).size()} + (number of
   * self-loops incident to {@code node}).
   *

# Windows .bat files are known to have multiple bugs when run with LF
# endings, and so they are checked in with CRLF endings, with a test
# in test/winbatch.go to catch problems. (See golang.org/issue/37791.)
#
# We'll prevent accidental CRLF line endings from entering the repo
# via the git-codereview gofmt checks and tests.
#
# See golang.org/issue/9281.
