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}
slider.dcr {the bitmap for the Slider component}
slider.dcu {the compiled Slider component}
slider.hlp {full documentation of the Slider component}
slider.int {the source of the interface part of slider.dcu}
slider.kwf {the keyword file of slider.hlp for integrating the PSLabel's help into the Delphi IDE; see How to install in slider.hlp}

readme.txt {this file}

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