How to get "hints" of software installed by Ports ?

[Aaron Lewis]

Hi,

  I installed some software from ports today , and it outputs some
useful information when finished.
  e.g where its config file is

  Due to some mistakes , i lost these "important" information , how do i see it again ?
 Is there any tricks to show out it directly ? I don't want to install it again ..

Any ideas will appreciate  ;-)
