See the ``options'' manual entry for details on the standard options.

Name: aaaassssppppeeeecccctttt
Class: AAAAssssppppeeeecccctttt
Command-Line Switch:----aaaassssppppeeeecccctttt
Specifies a non-negative integer value indicating desired aspect
ratio for the text. The aspect ratio is specified as
100*width/height. 100 means the text should be as wide as it is
tall, 200 means the text should be twice as wide as it is tall, 50
means the text should be twice as tall as it is wide, and so on.
Used to choose line length for text if wwwwiiiiddddtttthhhh option isn't specified.
Defaults to 150.
Name: jjjjuuuussssttttiiiiffffyyyy
Class: JJJJuuuussssttttiiiiffffyyyy
Command-Line Switch:----jjjjuuuussssttttiiiiffffyyyy
Specifies how to justify lines of text. Must be one of lllleeeefffftttt,
cccceeeennnntttteeeerrrr, or rrrriiiigggghhhhtttt. Defaults to lllleeeefffftttt. This option works together
with the aaaannnncccchhhhoooorrrr, aaaassssppppeeeecccctttt, ppppaaaaddddXXXX, ppppaaaaddddYYYY, and wwwwiiiiddddtttthhhh options to provide a
variety of arrangements of the text within the window. The aaaassssppppeeeecccctttt
and wwwwiiiiddddtttthhhh options determine the amount of screen space needed to
display the text. The aaaannnncccchhhhoooorrrr, ppppaaaaddddXXXX, and ppppaaaaddddYYYY options determine
where this rectangular area is displayed within the widget's window,
and the jjjjuuuussssttttiiiiffffyyyy option determines how each line is displayed within
that rectangular region. For example, suppose aaaannnncccchhhhoooorrrr is eeee and
jjjjuuuussssttttiiiiffffyyyy is lllleeeefffftttt, and that the message window is much larger than
needed for the text. The the text will displayed so that the left
edges of all the lines line up and the right edge of the longest
line is ppppaaaaddddXXXX from the right side of the window; the entire text
block will be centered in the vertical span of the window.
Name: wwwwiiiiddddtttthhhh
Class: WWWWiiiiddddtttthhhh

PPPPaaaaggggeeee 1111
mmmmeeeessssssssaaaaggggeeee((((3333TTTTkkkk)))) mmmmeeeessssssssaaaaggggeeee((((3333TTTTkkkk))))
Specifies the length of lines in the window. The value may have any
of the forms acceptable to TTTTkkkk____GGGGeeeettttPPPPiiiixxxxeeeellllssss. If this option has a value
greater than zero then the aaaassssppppeeeecccctttt option is ignored and the wwwwiiiiddddtttthhhh
option determines the line length. If this option has a value less
than or equal to zero, then the aaaassssppppeeeecccctttt option determines the line
length.

The mmmmeeeessssssssaaaaggggeeee command creates a new window (given by the _p_a_t_h_N_a_m_e argument)
and makes it into a message widget. Additional options, described above,
may be specified on the command line or in the option database to
configure aspects of the message such as its colors, font, text, and
initial relief. The mmmmeeeessssssssaaaaggggeeee command returns its _p_a_t_h_N_a_m_e argument. At
the time this command is invoked, there must not exist a window named
_p_a_t_h_N_a_m_e, but _p_a_t_h_N_a_m_e's parent must exist.
A message is a widget that displays a textual string. A message widget
has three special features. First, it breaks up its string into lines in
order to produce a given aspect ratio for the window. The line breaks
are chosen at word boundaries wherever possible (if not even a single
word would fit on a line, then the word will be split across lines).
Newline characters in the string will force line breaks; they can be
used, for example, to leave blank lines in the display.
The second feature of a message widget is justification. The text may be
displayed left-justified (each line starts at the left side of the
window), centered on a line-by-line basis, or right-justified (each line
ends at the right side of the window).
The third feature of a message widget is that it handles control
characters and non-printing characters specially. Tab characters are
replaced with enough blank space to line up on the next 8-character
boundary. Newlines cause line breaks. Other control characters (ASCII
code less than 0x20) and characters not defined in the font are displayed
as a four-character sequence \\\\xxxx_h_h where _h_h is the two-digit hexadecimal
number corresponding to the character. In the unusual case where the
font doesn't contain all of the characters in ``0123456789abcdef\x'' then
control characters and undefined characters are not displayed at all.

The mmmmeeeessssssssaaaaggggeeee command creates a new Tcl command whose name is _p_a_t_h_N_a_m_e.
This command may be used to invoke various operations on the widget. It
has the following general form:
_p_a_t_h_N_a_m_e _o_p_t_i_o_n ?_a_r_g _a_r_g ...?
_O_p_t_i_o_n and the _a_r_gs determine the exact behavior of the command. The
following commands are possible for message widgets:

_p_a_t_h_N_a_m_e ccccggggeeeetttt _o_p_t_i_o_n
Returns the current value of the configuration option given by |
_o_p_t_i_o_n. _O_p_t_i_o_n may have any of the values accepted by the mmmmeeeessssssssaaaaggggeeee |
command.
_p_a_t_h_N_a_m_e ccccoooonnnnffffiiiigggguuuurrrreeee ?_o_p_t_i_o_n? ?_v_a_l_u_e _o_p_t_i_o_n _v_a_l_u_e ...?
Query or modify the configuration options of the widget. If no
_o_p_t_i_o_n is specified, returns a list describing all of the available
options for _p_a_t_h_N_a_m_e (see TTTTkkkk____CCCCoooonnnnffffiiiigggguuuurrrreeeeIIIInnnnffffoooo for information on the
format of this list). If _o_p_t_i_o_n is specified with no _v_a_l_u_e, then
the command returns a list describing the one named option (this
list will be identical to the corresponding sublist of the value
returned if no _o_p_t_i_o_n is specified). If one or more _o_p_t_i_o_n-_v_a_l_u_e
pairs are specified, then the command modifies the given widget
option(s) to have the given value(s); in this case the command
returns an empty string. _O_p_t_i_o_n may have any of the values accepted
by the mmmmeeeessssssssaaaaggggeeee command.

When a new message is created, it has no default event bindings:
messages are intended for output purposes only.
BBBBUUUUGGGGSSSS
Tabs don't work very well with text that is centered or right-justified.
The most common result is that the line is justified wrong.
