Subject: caller


the follow code is in the mkmf.rb:

*def checking_for(m)
  f = caller[0][/in `(.*)'$/, 1] and f << ": " #` for vim
  m = "checking for #{m}... "
  message "%s", m
  a = r = nil
  Logging::postpone do
    r = yield
    a = r ? "yes\n" : "no\n"
    "#{f}#{m}-------------------- #{a}\n"
  end
  message(a)
  Logging::message "--------------------\n\n"
  r
end

*what meaning of the '*f = caller[0][/in `(.*)'$/, 1] and f << ": " #` for vim*'?

pls!
