### User-Agent Parsing Examples

Source: https://github.com/jaybizzle/crawler-detect/blob/master/tests/data/sec_ch_ua/crawlers.txt

Demonstrates parsing of User-Agent strings to identify browser versions and types. These examples are crucial for distinguishing between human users and automated bots.

```APIDOC
User-Agent String Parsing:

This section details the interpretation of common User-Agent strings used by browsers, particularly headless ones.

Example 1:
  Input: "HeadlessChrome";v="129", "Not=A?Brand";v="8", "Chromium";v="129"
  Analysis: Identifies 'HeadlessChrome' with version '129' and 'Chromium' with version '129'. The 'Not=A?Brand' is a placeholder.
  Purpose: Detects a specific version of Headless Chrome.

Example 2:
  Input: "HeadlessChrome";v="113", "Chromium";v="113", "Not-A.Brand";v="24"
  Analysis: Identifies 'HeadlessChrome' with version '113' and 'Chromium' with version '113'. 'Not-A.Brand' is a placeholder.
  Purpose: Detects an older version of Headless Chrome.

Example 3:
  Input: "Chromium";v="128", "Not;A=Brand";v="24", "HeadlessChrome";v="128"
  Analysis: Identifies 'Chromium' with version '128' and 'HeadlessChrome' with version '128'. 'Not;A=Brand' is a placeholder.
  Purpose: Detects another version of Headless Chrome.

General Parsing Rules:
  - User-Agent strings are comma-separated.
  - Each segment typically follows the format "ProductName";v="Version".
  - The presence and version of 'HeadlessChrome' are key indicators.
  - Placeholder brands like 'Not=A?Brand' should be ignored for detection purposes.
