This free Software includes two Delphi Controls (VCL)
- TKnob
- TMeter
so before you can use them, you must install them first in your Delphi IDE,
you can read the online help to accomplish the installation process

These VLCs was written in Delphi 3 and it might need (I haven't tried it yet) some adjustments,
and it would be relatively easy.

Thanks for trying this software and feel free to send me some comments.
