Sqlite is often used as a quick and dirty database by projects that don't want to burden their developers with the setup overhead of mysql or postgres. It's a tiny, rock-solid executable that stores data in a single binary file and supports sql access. Access to the file is globally locked. It's good enough for testing out a project on a single developer's machine but the global lock makes it hard to use in a multi-user production scenario. In a similar vein I could see git as a widely available, rock-solid, "quick and dirty" way for a project to store and retrieve documents.
