You have to include this .PAS in a PACKAGE (.DPK) - that is the source file of a .BPL file.
It can be either a new one, or an existing one.
Once this package compiled, you have to install it (if not already), and you will have a message telling you that some new components classes are registered.
Step by step :
1) File -> New -> Package
1a) Options : rename your package, add other options etc...
2) Project -> Add to project
select your .PAS file
3) Project -> Build Package
Some .BPL has just been created, you could then ise the Component menu to add your BPL
You can do Build+Instal in one step by right-clicking on the Package name where all file it contains are listed, and select "Instal"
