106%D The following colon related definitions are provided by Aditya
107%D Mahajan who derived them from \type {mathtools.sty} and \type
108%D {colonequals.sty}. This will be redone as part of the overhaul
109%D and font updates.
110%D
111%D In $a := b$ the colon is not vertically centered with the equal
112%D to. Also the distance between colon and equal to is a bit large.
113%D So, we define a vertically centered colon \tex {centercolon} and
114%D a few macros for colon and double colon relation symbols.
