+**  (14)  A separate percentile_cont(Y,P) function is equivalent to
-**        percentile(Y,X*100.0).
+**        percentile(Y,P/100.0).  In other words, the fraction value in
+**        the second argument is in the range of 0 to 1 instead of 0 to 100.
+**
+**  (15)  A separate percentile_disc(Y,P) function is like
+**        percentile_cont(Y,P) except that instead of returning the weighted
+**        average of the nearest two input values, it returns the next lower
+**        value.  So the percentile_disc(Y,P) will always return a value
+**        that was one of the inputs.
+**
+**  (16)  All of median(), percentile(Y,P), percentile_cont(Y,P) and
+**        percentile_disc(Y,P) can be used as window functions.
+**
+** Differences from standard SQL:
+**
+**  *  The percentile_cont(X,P) function is equivalent to the following in
+**     standard SQL:
+**
+**         (percentile_cont(P) WITHIN GROUP (ORDER BY X))
+**
+**     The SQLite syntax is much more compact.  The standard SQL syntax
+**     is also supported if SQLite is compiled with the
+**     -DSQLITE_ENABLE_ORDERED_SET_AGGREGATES option.
+**
+**  *  No median(X) function exists in the SQL standard.  App developers
+**     are expected to write "percentile_cont(0.5)WITHIN GROUP(ORDER BY X)".
+**
+**  *  No percentile(Y,P) function exists in the SQL standard.  Instead of
+**     percential(Y,P), developers must write this:
+**     "percentile_cont(P/100.0) WITHIN GROUP (ORDER BY Y)".  Note that
+**     the fraction parameter to percentile() goes from 0 to 100 whereas
+**     the fraction parameter in SQL standard percentile_cont() goes from
+**     0 to 1.
+**
+** Implementation notes as of 2024-08-31:
+**
+**  *  The regular aggregate-function versions of these routines work
+**     by accumulating all values in an array of doubles, then sorting
+**     that array using quicksort before computing the answer. Thus
+**     the runtime is O(NlogN) where N is the number of rows of input.
+**
+**  *  For the window-function versions of these routines, the array of
+**     inputs is sorted as soon as the first value is computed.  Thereafter,
+**     the array is kept in sorted order using an insert-sort.  This
+**     results in O(N*K) performance where K is the size of the window.
+**     One can imagine alternative implementations that give O(N*logN*logK)
+**     performance, but they require more complex logic and data structures.
+**     The developers have elected to keep the asymptotically slower
+**     algorithm for now, for simplicity, under the theory that window
+**     functions are seldom used and when they are, the window size K is
+**     often small.  The developers might revisit that decision later,
+**     should the need arise.

-should be invoked as follows:

-The default value for ::MAKEFILE is "../Makefile.linux.gcc".
-
-If -skip_run option is given then only the compile part is attempted.
-
-This script builds the testfixture program and runs the SQLite test suite
-once with each SQLITE_OMIT_ option defined and then once with all options
-defined together. Each run is performed in a seperate directory created
-as a sub-directory of the current directory by the script. The output
-of the build is saved in <sub-directory>/build.log. The output of the
-test-suite is saved in <sub-directory>/test.log.
-
-Almost any SQLite makefile (except those generated by configure - see below)
-should work. The following properties are required:
-
-  * The makefile should support the "testfixture" target.
-  * The makefile should support the "test" target.
-  * The makefile should support the variable "OPTS" as a way to pass
-    options from the make command line to lemon and the C compiler.
-
-More precisely, the following two invocations must be supported:
-
-  $::MAKEBIN -f $::MAKEFILE testfixture OPTS="-DSQLITE_OMIT_ALTERTABLE=1"
-  $::MAKEBIN -f $::MAKEFILE test
-
-Makefiles generated by the sqlite configure program cannot be used as
-they do not respect the OPTS variable.
