+@cindex automatic scrolling
   Emacs performs @dfn{automatic scrolling} when point moves out of the
-visible portion of the text.
+visible portion of the text.  Normally, automatic scrolling centers
+point vertically in the window, but there are several ways to alter
+this behavior.
 
 @vindex scroll-conservatively
-  Normally, this centers point vertically within the window.  However,
-if you set @code{scroll-conservatively} to a small number @var{n},
-then if you move point just a little off the screen (less than @var{n}
-lines), Emacs scrolls the text just far enough to bring point back on
-screen.  If doing so fails to make point visible, Emacs centers point
-in the window.  By default, @code{scroll-conservatively} is@tie{}0.
-If you set @code{scroll-conservatively} to a large number (larger than
-100), Emacs will never center point as result of scrolling, even if
-point moves far away from the text previously displayed in the window.
-With such a large value, Emacs will always scroll text just enough for
-bringing point into view, so point will end up at the top or bottom of
-the window, depending on the scroll direction.
+  If you set @code{scroll-conservatively} to a small number @var{n},
+then moving point just a little off the screen (no more than @var{n}
+lines) causes Emacs to scroll just enough to bring point back on
+screen; if doing so fails to make point visible, Emacs scrolls just
+far enough to center point in the window.  If you set
+@code{scroll-conservatively} to a large number (larger than 100),
+automatic scrolling never centers point, no matter how far point
+moves; Emacs always scrolls text just enough to bring point into view,
+either at the top or bottom of the window depending on the scroll
+direction.  By default, @code{scroll-conservatively} is@tie{}0, which
+means to always center point in the window.
 
 @vindex scroll-step
-  An alternative way of controlling how Emacs scrolls text is by
-customizing the variable @code{scroll-step}.  Its value determines how
-many lines to scroll the window when point moves off the screen.  If
-moving by that number of lines fails to bring point back into view,
-point is centered instead.  The default value is zero, which causes
-point to always be centered after scrolling.
-
-  Since both @code{scroll-conservatively} and @code{scroll-step}
-control automatic scrolling in contradicting ways, you should set only
-one of them.  If you customize both, the value of
-@code{scroll-conservatively} takes precedence.
+  Another way to control automatic scrolling is to customize the
+variable @code{scroll-step}.  Its value determines the number of lines
+by which to automatically scroll, when point moves off the screen.  If
+scrolling by that number of lines fails to bring point back into view,
+point is centered instead.  The default value is zero, which (by
+default) causes point to always be centered after scrolling.
 
 @cindex aggressive scrolling
 @vindex scroll-up-aggressively
 @vindex scroll-down-aggressively
-  When the window does scroll by a distance longer than
-@code{scroll-step}, you can control how aggressively it scrolls by
-setting the variables @code{scroll-up-aggressively} and
-@code{scroll-down-aggressively}.  The value of
-@code{scroll-up-aggressively} should be either @code{nil}, or a
-fraction @var{f} between 0 and 1.  A fraction specifies where on the
-screen to put point when scrolling upward, i.e.@: forward.  When point
-goes off the window end, the new start position is chosen to put point
-@var{f} parts of the window height from the bottom margin.  Thus,
-larger @var{f} means more aggressive scrolling: more new text is
-brought into view.  The default value, @code{nil}, is equivalent to
-0.5.
+  A third way to control automatic scrolling is to customize the
+variables @code{scroll-up-aggressively} and
+@code{scroll-down-aggressively}, which directly specify the vertical
+position of point after scrolling.  The value of
+@code{scroll-up-aggressively} should be either @code{nil} (the
+default), or a floating point number @var{f} between 0 and 1.  The
+latter means that when point goes below the bottom window edge (i.e.@:
+scrolling forward), Emacs scrolls the window so that point is @var{f}
+parts of the window height from the bottom window edge.  Thus, larger
+@var{f} means more aggressive scrolling: more new text is brought into
+view.  The default value, @code{nil}, is equivalent to 0.5.
 
-  Likewise, @code{scroll-down-aggressively} is used for scrolling
-down, i.e.@: backward.  The value specifies how far point should be
-placed from the top margin of the window; thus, as with
-@code{scroll-up-aggressively}, a larger value is more aggressive.
+  Likewise, @code{scroll-down-aggressively} is used when point goes

+specifies how far point should be from the top margin of the window
+after scrolling.  Thus, as with @code{scroll-up-aggressively}, a
+larger value is more aggressive.
 
-  These two variables are ignored if either @code{scroll-step} or
-@code{scroll-conservatively} are set to a non-zero value.
+  Note that the variables @code{scroll-conservatively},
+@code{scroll-step}, and @code{scroll-up-aggressively} /
+@code{scroll-down-aggressively} control automatic scrolling in
+contradictory ways.  Therefore, you should pick no more than one of
+these methods to customize automatic scrolling.  In case you customize
+multiple variables, the order of priority is:
+@code{scroll-conservatively}, then @code{scroll-step}, and finally
+@code{scroll-up-aggressively} / @code{scroll-down-aggressively}.

+
+If your program is working correctly, but you want to make it run more
+quickly or efficiently, the first thing to do is @dfn{profile} your
+code so that you know how it is using resources.  If you find that one
+particular function is responsible for a significant portion of the
+runtime, you can start looking for ways to optimize that piece.
+
+Emacs has built-in support for this.  To begin profiling, type
+@kbd{M-x profiler-start}.  You can choose to profile by processor
+usage, memory usage, or both.  After doing some work, type
+@kbd{M-x profiler-report} to display a summary buffer for each
+resource that you chose to profile.  The names of the report buffers
+include the times at which the reports were generated, so you can
+generate another report later on without erasing previous results.
+When you have finished profiling, type @kbd{M-x profiler-stop} (there
+is a small overhead associated with profiling).
+
+The profiler report buffer shows, on each line, a function that was
+called, followed by how much resource (processor or memory) it used in
+absolute and percentage times since profiling started.  If a given
+line has a @samp{+} symbol at the left-hand side, you can expand that
+line by typing @key{RET}, in order to see the function(s) called by
+the higher-level function.  Pressing @key{RET} again will collapse

 @cindex Julian calendar
 @cindex Gregorian calendar
 Some historical background:  The Julian calendar was created by
 Julius Caesar in the year 46 BC as an attempt to fix the confusion
 caused by the irregular Roman calendar that was used before that time.
-The Julian calendar introduced an extra day in
-all years divisible by four.  After some initial confusion, the
-calendar was adopted around the year we call 8 AD, although the years were
-numbered differently and did not necessarily begin on January 1.  Some centuries
-later it became apparent that the Julian year of 365.25 days was
-itself not quite right.  In 1582 Pope Gregory XIII introduced the
-Gregorian calendar, which added the new rule that years divisible
-by 100, but not by 400, were not to be considered leap years
-despite being divisible by four.  Many countries delayed adoption
-of the Gregorian calendar because of religious differences, and
-used differing year numbers and start-of-year for other reasons;
-for example, in early 1752 England changed the start of its year from
-March 25 to January 1, and in September it switched to the Gregorian
-calendar: in England, the day after December 31, 1750 was January 1,
-1750 and the day after March 24, 1750 was March 25, 1751, but the day
-after December 31, 1751 was January 1, 1752 and the day after
-September 2, 1752 was September 14, 1752.  To take another example,
-Russia switched both year numbering and start-of-year in 1700, but did
-not adopt the Gregorian calendar until 1918.  Calc's reckoning
-therefore matches English practice starting in 1752 and Russian
-practice starting in 1918, but disagrees with earlier dates in both
-countries.

+December 31, 1 BC as its day number 1; the new scheme is more

+
+	* find-cmd.el (find-constituents): Add executable, ipath,

+
+2012-11-23  Stefan Monnier  <monnier@iro.umontreal.ca>

+
+2012-11-22  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* calc/calc.el (calc-gregorian-switch): Move to after calc-refresh
+	definition.  This fixes a bootstrap failure.
+	(calc-gregorian-switch): In menu, put dates before regions.
+	This is easier to follow, lines up better in the menu, and lets us
+	coalesce regions that switch at the same time.  Give country
+	names, not "Vatican", as that's better for non-expert users.
+	Use names that are stable between the date of switch and now, e.g.,
+	Bohemia and Moravia (which existed then and now) and not
+	Czechoslovakia (which didn't exist then and doesn't exist now).
+	What is now the U.S. mostly did not switch at the same time as
+	Britain, so omit the U.S.  Correct spelling of "Britain".
+	Catholic Switzerland was too much of a mess, so omit it.
