-.SH DESCRIPTION
-.PP
-\fINote: this manual entry describes the syntax for the \fBpack\fI
-command as it existed before Tk version 3.3.
-Although this syntax continues to be supported for backward
-compatibility, it is obsolete and should not be used anymore.
-At some point in the future it may cease to be supported.\fR
-.PP
-The packer is a geometry manager that arranges the
-children of a parent by packing them in order around the edges of
-the parent. The first child is placed against one side of
-the window, occupying the entire span of the window along that
-side. This reduces the space remaining for other children as
-if the side had been moved in by the size of the first child.
-Then the next child is placed against one side of the remaining
-cavity, and so on until all children have been placed or there
-is no space left in the cavity.
-.PP
-The \fBbefore\fR, \fBafter\fR, and \fBappend\fR forms of the \fBpack\fR
-command are used to insert one or more children into the packing order
-for their parent. The \fBbefore\fR form inserts the children before
-window \fIsibling\fR in the order; all of the other windows must be
-siblings of \fIsibling\fR. The \fBafter\fR form inserts the windows
-after \fIsibling\fR, and the \fBappend\fR form appends one or more
-windows to the end of the packing order for \fIparent\fR. If a
-\fIwindow\fR named in any of these commands is already packed in
-its parent, it is removed from its current position in the packing
-order and repositioned as indicated by the command. All of these
-commands return an empty string as result.
-.PP
-The \fBunpack\fR form of the \fBpack\fR command removes \fIwindow\fR
-from the packing order of its parent and unmaps it. After the
-execution of this command the packer will no longer manage
-\fIwindow\fR's geometry.
-.PP
-The placement of each child is actually a four-step process;
-the \fIoptions\fR argument following each \fIwindow\fR consists of
-a list of one or more fields that govern the placement of that
-window. In the discussion below, the term \fIcavity\fR refers
-to the space left in a parent when a particular child is placed
-(i.e. all the space that was not claimed by earlier children in
-the packing order). The term \fIparcel\fR refers to the space
-allocated to a particular child; this is not necessarily the
-same as the child window's final geometry.
-.PP
-The first step in placing a child is to determine which side of
-the cavity it will lie against. Any one of the following options
-may be used to specify a side:
-.TP
-\fBtop\fR
-Position the child's parcel against the top of the cavity,
-occupying the full width of the cavity.
-.TP
-\fBbottom\fR
-Position the child's parcel against the bottom of the cavity,
-occupying the full width of the cavity.
-.TP
-\fBleft\fR
-Position the child's parcel against the left side of the cavity,
-occupying the full height of the cavity.
-.TP
-\fBright\fR
-Position the child's parcel against the right side of the cavity,
-occupying the full height of the cavity.
-.LP
-At most one of these options should be specified for any given window.
-If no side is specified, then the default is \fBtop\fR.
-.PP
-The second step is to decide on a parcel for the child. For \fBtop\fR
-and \fBbottom\fR windows, the desired parcel width is normally the cavity
-width and the desired parcel height is the window's requested height,
-as passed to \fBTk_GeometryRequest\fR. For \fBleft\fR and \fBright\fR
-windows, the desired parcel height is normally the cavity height and the
-desired width is the window's requested width. However, extra
-space may be requested for the window using any of the following
-options:
-.TP 12
-\fBpadx \fInum\fR
-Add \fInum\fR pixels to the window's requested width before computing
-the parcel size as described above.
-.TP 12
-\fBpady \fInum\fR
-Add \fInum\fR pixels to the window's requested height before computing
-the parcel size as described above.
-.TP 12
-\fBexpand\fR
-This option requests that the window's parcel absorb any extra space left over
-in the parent's cavity after packing all the children.
-The amount of space left over depends on the sizes requested by the
-other children, and may be zero. If several windows have all specified
-\fBexpand\fR then the extra width will be divided equally among all the
-\fBleft\fR and \fBright\fR windows that specified \fBexpand\fR and
-the extra height will be divided equally among all the \fBtop\fR and
-\fBbottom\fR windows that specified \fBexpand\fR.
-.LP
-If the desired width or height for a parcel is larger than the corresponding
-dimension of the cavity, then the cavity's dimension is used instead.
-.PP
-The third step in placing the window is to decide on the window's
-width and height. The default is for the window to receive either
-its requested width and height or the those of the parcel, whichever
-is smaller. If the parcel is larger than the window's requested
-size, then the following options may be used to expand the
-window to partially or completely fill the parcel:
-.TP
-\fBfill\fR
-Set the window's size to equal the parcel size.
-.TP
-\fBfillx\fR
-Increase the window's width to equal the parcel's width, but retain
-the window's requested height.
-.TP
-\fBfilly\fR
-Increase the window's height to equal the parcel's height, but retain
-the window's requested width.
-.PP
-The last step is to decide the window's location within its parcel.
-If the window's size equals the parcel's size, then the window simply
-fills the entire parcel. If the parcel is larger than the window,
-then one of
-the following options may be used to specify where the window should
-be positioned within its parcel:
-.TP 15
-\fBframe center\fR
-Center the window in its parcel. This is the default if no framing
-option is specified.
-.TP 15
-\fBframe n\fR
-Position the window with its top edge centered on the top edge of
-the parcel.
-.TP 15
-\fBframe ne\fR
-Position the window with its upper-right corner at the upper-right corner
-of the parcel.
-.TP 15
-\fBframe e\fR
-Position the window with its right edge centered on the right edge of
-the parcel.
-.TP 15
-\fBframe se\fR
-Position the window with its lower-right corner at the lower-right corner
-of the parcel.
-.TP 15
-\fBframe s\fR
-Position the window with its bottom edge centered on the bottom edge of
-the parcel.
-.TP 15
-\fBframe sw\fR
-Position the window with its lower-left corner at the lower-left corner
-of the parcel.
-.TP 15
-\fBframe w\fR
-Position the window with its left edge centered on the left edge of
-the parcel.
-.TP 15
-\fBframe nw\fR
-Position the window with its upper-left corner at the upper-left corner
-of the parcel.
-.PP
-The packer manages the mapped/unmapped state of all the packed
-children windows. It automatically maps the windows when it packs
-them, and it unmaps any windows for which there was no space left
-in the cavity.
-.PP
-The packer makes geometry requests on behalf of the parent windows
-it manages. For each parent window it requests a size large enough
-to accommodate all the options specified by all the packed children,
-such that zero space would be leftover for \fBexpand\fR options.
