Offending files

| File | Note |
|---|---|
| marktree.js | |
| mm2oowriter.xsl | |
| tohtml.xsl | |
| toxhtml.xsl. |
Copyright notice in code
A source file may be viewed as a sum b + d1 + d2 + ... + dk, where b is the basis, di are deltas (or patches), and the plus operator is the operator of applying a patch. The basis and each delta have their own copyright holder and the year of copyright.
If there is only one author and one year, then the copyright notice is simple.
If there is only one author and more years, then the copyright notice may look like
Copyright © 2003-2005 Big Author
which is to be understood as
Some parts of the sum are copyrighted in 2003, some perhaps in 2004, and some certainly in 2005.
If there are more authors, then the copyright notice consists of more lines, like
Copyright © 2003-2005 Big Author, Copyright © 2005 Captain,
Not all changes are eligible for copyright. If a change is small, then it does not make sense to add a line to the copyright notice for it.
Copyright notice is not required for copyright to hold. It makes claiming your right at court easier.
The correctness of these instructions is not granted. They are subject to improvement as we see fit.
