'51D_REPO_PATH' with the path to the 51Degrees repository.
-51Degrees provide 2 different detection algorithms:
+51Degrees provide 3 different detection algorithms:
1. Pattern - balances main memory usage and CPU.
2. Trie - a very high performance detection solution which uses more main
memory than Pattern.
+ 3. Hash Trie - replaces Trie, 3x faster, 80% lower memory consumption and
+ tuning options.
To make with 51Degrees Pattern algorithm use the following command line.
