is a line containing the control character followed by a two

produced on standard output. The formatting commands are listed

relevant, are given in parentheses.
.ad Adjust right margin.

.cc c Control character is set to c.
.ce n Center the next n input lines.
.de zz Define a macro called zz. A line with .. ends definition.

.ef t Even page footer title is set to t.
.eh t Even page header title is set to t.
.fi Begin filling output lines as full as possible.
.fo t Footer titles (even and odd) are set to t.
.hc c The character c (e.g., %) tells roff where hyphens are permitted.
.he t Header titles (even and odd) are set to t.
.hx Header titles are suppressed.

.ig Ignore input lines until a line beginning with .. is found.
.in n Indent n spaces from the left margin; force line break.
.ix n Same as .in but continue filling output on current line.
.li n Literal text on next n lines. Copy to output unmodified.
.ll +n Line length (including indent) is set to n (65).
.ls +n Line spacing: n (1) is 1 for single spacing, 2 for double, etc.
.m1 n Insert n (2) blank lines between top of page and header.

.m3 n Insert n (1) blank lines between end of text and footer.
