/*******************************************************************************
* A brief history of JavaDoc-style (C-style) banner comments.
*
* This is the typical JavaDoc-style C-style "banner" comment. It starts with
* a forward slash followed by some number, n, of asterisks, where n > 2. It's
* written this way to be more "visible" to developers who are reading the
* source code.
*
* Often, developers are unaware that this is not (by default) a valid Doxygen
* comment block!
*
* However, as long as JAVADOC_BLOCK = YES is added to the Doxyfile, it will
* work as expected.
*
* This style of commenting behaves well with clang-format.
*
* @param theory Even if there is only one possible unified theory. it is just a
* set of rules and equations.

/***************************************************************************//**
* A brief history of Doxygen-style banner comments.
*
* This is a Doxygen-style C-style "banner" comment. It starts with a "normal"
* comment and is then converted to a "special" comment block near the end of
* the first line. It is written this way to be more "visible" to developers
* who are reading the source code.
* This style of commenting behaves poorly with clang-format.

* @param theory Even if there is only one possible unified theory. it is just a
