[erlang-questions] Why can an unresolved function be called in lager?

[Michael Scofield]

Hi all:
I am new to Erlang, and now using lager <https://github.com/basho/lager> as
my logging tools.
I went through the lager.erl file, and found there's no exported function
called info/1. However, I can call lager:info/1 from the shell, it works
fine. How can this possible?
Thx!
