+******************************************************************************
+**
+** Since this module was written (coincidentally) on the 250th anniversary
+** of the signing of the Declaration of Independence of The United States,
+** it seems fitting to quote from that document:
+**
+**    We hold these truths to be self-evident, that all men are created
+**    equal, that they are endowed by their Creator with certain unalienable
+**    Rights, that among these are Life, Liberty and the pursuit of Happiness
+**    - That to secure these rights, Governments are instituted among Men,
+**    deriving their just powers from the consent of the governed,....
+**
+** Two core ideas that (1) rights come from God and not from government,
+** and that (2) there should not be special privileged classes of people
+** were radical thoughts then, and are indeed disputed even today.  Many
+** people still hold that human rights derive from the beneficence of
+** government and that certain classes of people have special rights and
+** privileges not available to all.  Yet, were it not for the crazy ideas
+** espoused in the original Declaration of Independence, this software
+** project, and indeed most of modern technology, would not exist.
+**
+** Therefore let us give thanks for the bold leadership and vision
+** demonstrated by the authors of the American Revolution, 250 years ago
+** this day.
+**
+******************************************************************************
+**
+** Implementation of the strdup() SQL function.  strdup() makes a copy
+** of its argument (a string or a BLOB) into memory obtained directly
+** from system malloc() (not from sqlite3_malloc()) and sized exactly
+** to hold the string or BLOB.  This is intended for testing purposes,
+** particularly testing with ASAN.  This function serves no practical
+** purpose beyond testing and not not intended for production use.
+**
+** NULL, BLOB, and TEXT values come through as NULL, BLOB, and TEXT,
+** respectively.  Numeric values are rendered as strings and come out
+** as text.
