#     ./bin/generator.sh       # To generate stubs with latest code from the master branch of Swoole.
#     ./bin/generator.sh 4.4.7 # To generate stubs for a specific version of Swoole.
#
# You can also specify a 2nd parameter, indicating which Swoole libary version to be integrated in. By default it will
# have latest Swoole libary included (from the master branch). e.g.,
#     ./bin/generator.sh 4.4.13 master
#     ./bin/generator.sh 4.4.13 a236ce004518e166b483d8d72cf5cc9ac2282164
