Thanks for your interested on the Perseus VCP!

The ZIP-file you've got should consist of the following files:

face.dcu   {the compiled DrawFace method}
face.int   {the source of the interface part of face.dcu}
pscctl.dcu {the unit of the parent of all Perseus components}
pscctl.int {the source of the interface part of pscctl}
wheel.dcr  {the bitmap for the Wheel component}
wheel.dcu  {the compiled Wheel component}
wheel.hlp  {full documentation of the Wheel component}
wheel.int  {the source of the interface part of wheel.dcu}
wheel.kwf  {the keyword file of wheel.hlp for integrating the PSLabel's help into the Delphi IDE; see How to install in wheel.hlp}

readme.txt {this file}

You should read the helpfile first. There are special topics which should help you with installing and testing!
