.\" ***** hack to get roman numerals in toc footer (JDF 10/90)
.\"
.\" Apparently, just setting the page register % to roman format
.\" doesn't work. It seems the value of a roman % in an "if" expression
.\" always returns zero (troff bug?). This behavior breaks -ms when
.\" it tests % during header and footer printing. So, instead of reformatting %,
.\" we create a private roman format register Pg that will be set to % at Bg and Ed.
.\" We might just miss a page change but, hey, this is a hack.
.\" To start at a page other than 1, set the Pg register to the start page
.\" number prior to sourcing this file.
