Here's a Python script to upload multiple files using the provided OpenAPI specification:

import requests

def upload_documents(client_token, files):
    url = "https://api.example.com/documents"
    headers = {
        "Authorization": f"Bearer {client_token}"
    }
    
    # Prepare the files for upload
    documents = []
    for file_path in files:
        with open(file_path, "rb") as f:
            file_content = f.read()
        
        document = {
            "content": {
                "documentIdentifier": file_path.split("/")[-1],
                "parseImage": False,
                "inlineContent": {
                    "byteContent": {
                        "data": file_content,
                        "mimeType": "application/octet-stream"
                    },
                    "type": "BYTE"
                }
            },
            "metadata": {
                "inlineAttributes": [
                    {
                        "key": "filename",
                        "value": file_path.split("/")[-1]
                    }
                ]
            }
        }
        documents.append(document)
    
    # Create the request body
    request_body = {
        "clientToken": client_token,
        "documents": documents
    }
    
    # Send the POST request
    response = requests.post(url, headers=headers, json=request_body)
    
    return response.json()

# Example usage
client_token = "your-client-token"
files = ["path/to/file1.txt", "path/to/file2.txt"]
response = upload_documents(client_token, files)
print(response)


### Explanation:
1. **Function Definition**: The `upload_documents` function takes `client_token` and `files` as parameters.
2. **URL and Headers**: The URL for the API endpoint and the authorization headers are set.
3. **File Preparation**: Each file is read and its content is added to the `documents` list with the necessary metadata.
4. **Request Body**: The request body is created with the `clientToken` and `documents`.
5. **POST Request**: The POST request is sent to the API endpoint with the request body.

Replace `"your-client-token"` with your actual client token and update the file paths in the `files` list.
