========================
Every year newly updated files need to have its copyright headers updated to reflect the current year.
If you run this script from src/ it will automatically update the year on the copyright header for all
.cpp and .h files if these have a git commit from the current year.
If you run this script from the root folder it will automatically update the year on the copyright header for all
source files if these have a git commit from the current year.
For example a file changed in 2014 (with 2014 being the current year):
For example a file changed in 2015 (with 2015 being the current year):
```// Copyright (c) 2009-2013 The Bitcoin Core developers```
would be changed to:
```// Copyright (c) 2009-2014 The Bitcoin Core developers```
```// Copyright (c) 2009-2015 The Bitcoin Core developers```

Run this script inside of src/ and it will look for all the files
that were changed this year that still have the last year in the
copyright headers, and it will fix the headers on that file using
a perl regex one liner.
Run this script to update all the copyright headers of files
that were changed this year.
For example: if it finds something like this and we're in 2014
For example:
// Copyright (c) 2009-2013 The Bitcoin Core developers
// Copyright (c) 2009-2012 The Bitcoin Core developers
it will change it to
// Copyright (c) 2009-2014 The Bitcoin Core developers
It will do this for all the files in the folder and its children.
