.SH DESCRIPTION
.I Boxify 
is a filter taking any CIF-file as standard input and generates a
CIF-file containing only boxes as basic geometric figure on standard output.
Non-manhatten (Bostonian) geometry is estimated with boxes. The
quality of the estimation is determined by the resolution in the input
geometry. To improve box-estimation the layout may be scaled with the
\-s switch. Remember boxes are specified by length, width and
center-point while polygons are specified by edge-points. 
Additional features are: 1) ordering of symbols
making definitions appear before calls, 2) separating hierarchy
{symbols contains only calls or boxes, never both). These requirements
should make any CIF-file loadable for simple box-shufflers like WoL.
Both overlapping geometry and zero-area boxes are removed.

.I WARNING:
This program should be used with care and understanding since quite 
serious changes are done to the CIF-code.
.PP
.I Boxify
options are :
.TP
.B \-s \ scalemultiplier scaledevider
is a scaling-factor applied to all points in the layout when writing
the CIF-file. Does not affect scaling in DS.
.TP
.B \-c \ scalemultiplier scaledevider
This is the scalefactor written in the DS-command. WOL likes -c 100 2.
.TP
.B \-p \ scalemultiplier scaledevider
is a prescaling-factor applied to all points when reading. In this way
box-approximation may be improved. For MOSIS design-rules at least \-s
4 1 should be used.
.TP
.BI \-n
Cells are named with user-command: 9. Some editors (like WoL) requires
named cells. The name will be generated as "Cell<number>" where <number> is 
generated by the program.
.TP
.BI \-N \ cellname
Cells are named with user-command: 9. Some editors (like WoL) requires
named cells. The name will be "cellname<number>".
.TP
.BI \-b 
Multiplies all symbol-scaling to coordinates.
.TP
.BI \-d \ usercommand
is used to remove special usercommands causing  problems for your favorite
layouteditor. This switch may be applied more than once.
.TP
.BI \-o
Normally coordinate-systems for cells are transformed to (0,0) in lower
left corner. This switch preserves the original coordinate-system.
.TP
.BI \-z
With this switch zero-area boxes are dropped. Otherwise a warning is issued. 
.TP
.BI \-h
Turns off separation of hierarcy including geometry in cells with calls to other cells.
.SH examples:
For MOSIS design-rules the following command may be used.
.TP
boxify -p 4 1 -b -n -c 100 2 < scrules12.cif > scr12.cif
