Groff Machinery

The following example illustrates the power of the groff program as a wrapper around troff. To process a roff file using the preprocessors tbl and pic and the me macro set, classical troff had to be called by pic foo.me tbl troff -me -Tlatin1 grotty Using groff, this pipe can be shortened to the equivalent command groff -p -t -me -T latin1 foo.me An even easier way to call this is to use grog(1) to guess the preprocessor and macro options and execute the generated command (by using backquotes to specify shell command substitution) `grog -Tlatin1 foo.me` The simplest way is to view the contents in an automated way by calling groffer foo.me.
