title: Delphi Path Variables
body: <p>In the Delphi IDE, the path to the Delphi installation is specified as $(DELPHI).  I am wondering if there is a way to create my own path indicators, such as $(MY_LIBRARY) or something similar. I thought $(DELPHI) was specified as an environment variable, but apparently not. Any ideas? (I'm using Delphi 7)</p>
