WebKitGTK+ Reference Manual: Environment

## Environment Environment — How does the environment affect applications that use WebKitGTK+ |

### Logging

You can make WebKitGTK+ log some of what it is doing internally by using the `WEBKIT_DEBUG` environment variable. It takes a space-separated list of names, representing the various aspects of the work the library performs. Notice that most of the logging is only done in debug builds (that you get when you pass `--enable-debug` to the `configure` script).

A list of possible values for the environment variable follows:
