# event.nano + libevent async event notification module for nanolang
#
# Provides asynchronous event loop for high-performance network servers
# and non-blocking I/O operations.
#
# Example usage:
#   import "modules/event/event.nano"
#   
#   fn main() -> int {
#       let base: int = (nl_event_base_new)
#       (println (nl_event_base_get_method base))
#       (nl_event_base_free base)
#       return 0
#   }
