from https://learnyousomeerlang.com/the-count-of-applications

1. erl -make each application
2. start erlang by =erl -env ERL_LIBS “.”=
3. start apps in correct order application:start(ppool), application:start(erlcount).

• we can override env variables like

  erl -env ERL_LIBS "." -erlcount directory '"/some/place/"' regex '["foo","bar"]'
