Skinner is a Delphi component set designed to ease the creation of applications with skins.
v0.5 provides high graphical abilities, but low "skinning" capabilities (that's why it's v0.5).
To use Skinner, you must download and install the FastLIB component set, available from the Skinner site.
Also, it is advisable to download and read the FastCourse tutorial; FastCourse-project-files-1.00.zip contains the ready version of the tutorial.
