Thanks. I'm familiar with troff, but somehow never came across pic in that context. I have some reading to do!

  One of the first “real” applications of Unix was in the AT&T documentation department. It not only reinforced the practicality of the Unixy “small tools linked by pipes” approach, it also encouraged the “little languages” approach to those tools, which brought us lex and yacc as people built things like eqn and pic to feed into troff. To discover more, just google “unix little languages”.
