-- notes ---------------------------------------------------------------------
the units included in this archive should work with delphi 5 through delphi
xe2 for win32.
the units included in this archive with the exception of zlibexgz should
work with delphi xe2 for win64.
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.
