=head1 DESCRIPTION
color() takes any number of strings as arguments and considers them to be
space-separated lists of attributes. It then forms and returns the escape
-sequence to set those attributes. It doesn't print it out, just returns it,
-so you'll have to print it yourself if you want to (this is so that you can
-save it as a string, pass it to something else, send it to a file handle, or
-do anything else with it that you might care to).
+sequence to set those attributes. It doesn't print it out, just returns
+it, so you'll have to print it yourself if you want to (this is so that
+you can save it as a string, pass it to something else, send it to a file
+handle, or do anything else with it that you might care to).
uncolor() performs the opposite translation, turning escape sequences
into a list of strings.
-The recognized attributes (all of which should be fairly intuitive) are clear,
-reset, dark, bold, underline, underscore, blink, reverse, concealed, black,
-red, green, yellow, blue, magenta, cyan, white, on_black, on_red, on_green,
-on_yellow, on_blue, on_magenta, on_cyan, and on_white. Case is not
-significant. Underline and underscore are equivalent, as are clear and reset,
-so use whichever is the most intuitive to you. The color alone sets the
-foreground color, and on_color sets the background color.
+The recognized non-color attributes are clear, reset, bold, dark, faint,
+underline, underscore, blink, reverse, and concealed. Clear and reset
+(reset to default attributes), dark and faint (dim and saturated), and
+underline and underscore are equivalent, so use whichever is the most
+intuitive to you. The recognized foreground color attributes are black,
+red, green, yellow, blue, magenta, cyan, and white. The recognized
+background color attributes are on_black, on_red, on_green, on_yellow,
+on_blue, on_magenta, on_cyan, and on_white. Case is not significant.
Note that not all attributes are supported by all terminal types, and some
-terminals may not support any of these sequences. Dark, blink, and
-concealed in particular are frequently not implemented.
+terminals may not support any of these sequences. Dark and faint, blink,
+and concealed in particular are frequently not implemented.
Attributes, once set, last until they are unset (by sending the attribute
-"reset"). Be careful to do this, or otherwise your attribute will last
-after your script is done running, and people get very annoyed at having
-their prompt and typing changed to weird colors.
-
-As an aid to help with this, colored() takes a scalar as the first argument
-and any number of attribute strings as the second argument and returns the
-scalar wrapped in escape codes so that the attributes will be set as
-requested before the string and reset to normal after the string.
-Alternately, you can pass a reference to an array as the first argument, and
-then the contents of that array will be taken as attributes and color codes
-and the remainder of the arguments as text to colorize.

+Alternately, you can pass a reference to an array as the first argument,
+and then the contents of that array will be taken as attributes and color
+codes and the remainder of the arguments as text to colorize.
Normally, colored() just puts attribute codes at the beginning and end of
the string, but if you set $Term::ANSIColor::EACHLINE to some string, that
$Term::ANSIColor::EACHLINE to C<"\n"> to use this feature.
Alternately, if you import C<:constants>, you can use the constants CLEAR,
-RESET, BOLD, DARK, UNDERLINE, UNDERSCORE, BLINK, REVERSE, CONCEALED, BLACK,
-RED, GREEN, YELLOW, BLUE, MAGENTA, CYAN, WHITE, ON_BLACK, ON_RED, ON_GREEN,
-ON_YELLOW, ON_BLUE, ON_MAGENTA, ON_CYAN, and ON_WHITE directly. These are
-the same as color('attribute') and can be used if you prefer typing:
+RESET, BOLD, DARK, UNDERLINE, UNDERSCORE, BLINK, REVERSE, CONCEALED,
+BLACK, RED, GREEN, YELLOW, BLUE, MAGENTA, CYAN, WHITE, ON_BLACK, ON_RED,
+ON_GREEN, ON_YELLOW, ON_BLUE, ON_MAGENTA, ON_CYAN, and ON_WHITE directly.
+These are the same as color('attribute') and can be used if you prefer
+typing:
print BOLD BLUE ON_WHITE "Text", RESET, "\n";
print BOLD BLUE "Text\n";

twenty-two in the constants interface. On the flip side, the constants
interface has the advantage of better compile time error checking, since
misspelled names of colors or attributes in calls to color() and colored()
-won't be caught until runtime whereas misspelled names of constants will be
-caught at compile time. So, pollute your namespace with almost two dozen
-subroutines that you may not even use that often, or risk a silly bug by
-mistyping an attribute. Your choice, TMTOWTDI after all.

+bug by mistyping an attribute. Your choice, TMTOWTDI after all.
+
+As of Term::ANSIColor 2.0, you can import C<:pushpop> and maintain a stack
+of colors using PUSHCOLOR, POPCOLOR, and LOCALCOLOR. PUSHCOLOR takes the
+attribute string that starts its argument and pushes it onto a stack of
+attributes. POPCOLOR removes the top of the stack and restores the
+previous attributes set by the argument of a prior PUSHCOLOR. LOCALCOLOR
+surrounds its argument in a PUSHCOLOR and POPCOLOR so that the color
+resets afterward.
+
+When using PUSHCOLOR, POPCOLOR, and LOCALCOLOR, it's particularly
+important to not put commas between the constants.
+
+ print PUSHCOLOR BLUE "Text\n";
+
+will correctly push BLUE onto the top of the stack.
+
+ print PUSHCOLOR, BLUE, "Text\n"; # wrong!
+
+will not, and a subsequent pop won't restore the correct attributes.
+PUSHCOLOR pushes the attributes set by its argument, which is normally a
+string of color constants. It can't ask the terminal what the current
+attributes are.

The codes generated by this module are standard terminal control codes,
-complying with ECMA-48 and ISO 6429 (generally referred to as "ANSI color"
-for the color codes). The non-color control codes (bold, dark, italic,
-underline, and reverse) are part of the earlier ANSI X3.64 standard for
-control sequences for video terminals and peripherals.
