C ugly hack: doc2ms uses $ as delimiter for eqn's so it doesn't seem to
C be able to print them. So we have to typeset this table without using
C eqn (at least that's the only solution I found, without any real docs
C on *roff and eqn
C First, terminate the table doc2ms.c already started:
%c c l .
%.TE
C ... then turn off eqn delimiters:
%.EQ
%delim off
%.EN
C ... and restart the table:
%.TS
