DOCTYPE(1) DOCTYPE(1)
NAME
doctype - guess command line for formatting a document
SYNOPSIS
doctype [ -e ] [ file ] ...
DESCRIPTION
Doctype guesses the command line necessary for printing a
document that uses troff(1), related preprocessors like eqn,
and the -ms and -mm macro packages. The optional argument
-e causes the command line to be executed.
SEE ALSO
troff(1), eqn(1), tbl(1), refer(1), pic(1), ideal(1),
grap(1), ms(7), mm(7)
BUGS
It's pretty dumb about guessing the proper macro package.
There is no way to supply non-filename arguments when -e is
used.
