A simple program designed to bundle multi-file C++ programs into a single file, allowing them to be submitted on platforms such as codeforces.
The cpp-roller program makes certain assumptions about how your code is written. It only "rolls" the include statements which use quotation marks (that's how it differentiates system headers from file includes). This is just a text-based tool, so any conditional incldues, such as those inside an ifndef clause, might cause unexpected behavior and should be avoided.
