-- notes ---------------------------------------------------------------------

  the zlibex.pas unit included in this archive will work with delphi 5, 6,
  and 7.  if you previously downloaded my delphi 5 unit, you will notice
  that the unit has been renamed.  this was done because borland included in
  its delphi 6 and 7 lib directories a zlib.dcu file; and i felt it was more
  correct to rename my unit and force developers to have to update their
  code than to make developers worry about the possible file contention in
  delphi 6 and 7.

  please contact me if you find any errors, make any changes, add new
  functionality, or have any general suggestions so that i may incorporate
  them into my version.  i can be reached via my website at
  http://www.base2ti.com.

  thanks.

-- installation --------------------------------------------------------------

  first, copy all of the files into a folder (for example, c:\delphi\zlib).
  next, include the folder in the library path in the environment options.
  finally, "use" the zlibex unit as needed.
