# # Column Box
#
# This example shows how [HexaPDF::Layout::ColumnBox] can be used to place
# contents into columns.
#
# Three boxes are placed repeatedly onto the frame until it is filled: two
# floating boxes (one left, one right) and a text box. The text box is styled to
# flow its content around the other two boxes.
#
# Usage:
# : `ruby column_box.rb`
#
