--------------------------------------------------------------------------
			       xiterm XPM
--------------------------------------------------------------------------

For the XPM XTerm escape sequence, "ESC ] 20; Pt BEL", Pt can be the
name of the background pixmap followed by a sequence of
scaling/positioning commands separated by semi-colons.

The scaling/positioning commands:
	`?'		= query scale/position
	`WxH+X+Y'	= change scale and position
	`WxH+X'		-> Y = X
	`WxH'		-> Y = X = 50
	`W+X+Y'		-> H = W
	`W+X'		-> H = W, Y = X
	`W'		-> H = W, X = Y = 50
	`=+X+Y'		= change position (absolute)
	`+X+Y'		= change position (relative)
	`=+X'		-> Y = X
	`+X'		-> Y = X
	`Wx0'		-> W *= W/100
	`0xH'		-> H *= H/100

For example:
eg.
	"\E]20;mona.xpm;200"
	loads the pixmap `mona.xpm' and sets the scaling to 200%
or
	"\E]20;;200;?\a"

	sets the scaling of the current pixmap to 200% and displays
	the image geometry in the title.

--------------------------------------------------------------------------
			       xiterm menuBar
--------------------------------------------------------------------------

For the menubar XTerm escape sequence, "ESC ] 10; Pt BEL", the syntax
of Pt is as follows:

	= title				set menuBar title
 	+/				access menuBar top level
 	-/				remove menuBar top level
	NUL				remove menuBar top level

	+ [/menu/path/]submenu		add/access menu
	- [/menu/path/]submenu		remove menu

	+ [/menu/path/]{item}[{rtext}] [action]	  add/alter item
	- [/menu/path/]{item}		remove item

	+ [/menu/path/]{-}		add separator
	- [/menu/path/]{-}		remove separator

	+ ../				access parent menu (1 level)
	+ ../../			access parent menu (multiple levels)

	Define menu quick arrows
	<b>Begin<r>Right<l>Left<u>Up<d>Down<e>End

NB: the square brackets indicate optional values.

The title may contain the following format specifiers:
            %%   literal '%' character
            %v   xiterm version

In the `action' associated with a menu item, special characters must be
backslash-escaped:
	`\a', `\b', `\E `\e', `\n', `\r', `\t', '\octal'
or in control-character notation:
	^@, ^A .. ^Z .. ^_, ^?

	If `action' begins with a NUL (^@) character followed by
	non-NUL characters, the leading NUL is stripped off and the
	balance is sent back to xiterm.

	To send a string starting with a NUL (^@) character to the
	program, start action with a pair of NUL characters (^@^@),
	the first of which will be stripped off and the balance
	directed to the program.

	As a concession and a convenience to the many Emacs work-alike
	editors, an action string can be be starting with the following:
		`M-...',	eg, `M-$'	== `\E$'
	and for Meta-x commands, a carriage-return will be appended if
	missing and leading space will be skipped

		eg, `M-x apropos' == `\Exapropos\r'

	The option {rtext} will be right-justified. In the absence of
	a specified action, this text will be as the used. So, for
	example,
		Pt = `+{Open}{^X^F}'
	is equivalent to
		Pt = `+{Open){^X^F}{^X^F}'

	To only have the right-justified text, either use the same name
	for both left and right labels, eg:
		Pt = `+{Open}{Open} Open-File-Action'
	or simply hide the left label by preceeding it with a dot, eg:
		Pt = `+{.anyLabel}{Open} Open-File-Action'

	Since the left label is used for matching, it is necessary.

	The menus also provide a hook for `quick arrows' to provide
	easier user access.  If nothing has been explicitly set, the
	default is to emulate the curror keys.	The syntax permits
	each arrow to be altered individually or all four at once with
	re-entering their common beginning/end text.  For example, to
	explicitly associate cursor actions with the arrows, any of the
	following forms could be used:

		Pt = `<u>\\E[A'
		Pt = `<d>\\E[B'
		Pt = `<r>\\E[C'
		Pt = `<l>\\E[D'
	or
		Pt = `<u>\\E[A<d>\\E[B<r>\\E[C<l>\\E[D'
	or
		Pt = `<b>\\E[<u>A<d>B<r>C<l>D'

	It is probably easiest just to see the examples.
