Creation of application system installer

System and method for creating an application system installer. A root deployable for an application system is received, and programmatically analyzed to determine a root deployer. The root deployer is programmatically analyzed to determine zero or more deployables, and one or more files-to-install. For each respective deployable, a respective deployer is programmatically determined that analyzes the respective deployable to determine any further deployables and files-to-install. This process is repeated for each of the further deployables until all deployables for the respective deployable have been determined and analyzed, and all files-to-install have been determined. The application system installer is then generated using the determined files-to-install, where the installer is operable to programmatically deploy the application system onto a target system to perform the function. Determining zero or more deployables may also include determining one or more supporting sub-installers, where the installer is then generated using the determined files-to-install and supporting sub-installers.
