exception error: undefined function

[zackpetersen]

I've downloaded the latest binary from https://github.com/inaka/elvis/releases/download/0.2.5-beta/elvis
When calling from the command line, I get the following error.

[vagrant@local-dev-rhel]$ ./elvis rock --config ./elvis.config
escript: exception error: undefined function elvis:main/1
  in function  escript:run/2 (escript.erl, line 747)
  in call from escript:start/1 (escript.erl, line 277)

I also tried the 0.2.3 binary and experienced similar results. However, it does produce the help menu when called with no arguments.

@zackpetersen What version of Erlang/OTP do you have installed?

Looks like I have R16B03-1. I see the problem now :)
