Help Builder supports Add-Ins via the Add-Ins option on the Tools menu bar and via the Add-in Manager. You can add Add-Ins and fire these Add-Ins as needed. Add-Ins can be created with the following:

• .NET Assemblies
  
• Visual FoxPro PRGs and APP files
  
• COM DLLs
  

Once created the new Add-in manager allows to install or import add-in definitions easily.
