title: Delphi XE2 .Z Unix compressed files library
body: <p>I need to manage .Z (Unix compressed) files, mainly dezip function.
  What is the best library to do this ?
  Prefere to avoid Dll (like 7z.dll).
  Edit : Today I have a solution with JCL compression library interfaced to 7z.dll.
  I just wanted to look for a more light &amp; simple solution as I just need the '.Z' decopression function.</p>
