What is a bootstrapper?

I know what the term means when it comes to operating systems, but what about software?

I have a program that has a startup file. This file is THE very first thing that gets ran before anything else does. All this file does is starts is run a variety of checks against the current computer including hardware and the OS making sure that the environment is safe and stable and if another process is already running. After that it starts a local TCP server for broadcasting messages for developers, and after that the program starts working. If anything is not up to spec the program will nicely shutdown. If everything checks out, it will start the applications main loop. My app, which acts as a background service runs on a single loop.

Is this startup file considered a bootstrapper? Seeing how it is checking things and preparing things for the program to run?
