% man xo_finish

Calling this function is vital to the proper operation of libxo,
especially for the non-TEXT output styles.
...
Note, the word "vital" is underlined in xterm for emphasis.
PS: To whomever is responsible for libxo, some (most?) libxo
manpages have the wrong NAME information. For example,
% man xo_finish
LIBXO(3) FreeBSD Library Functions Manual LIBXO(3)
NAME
xo_emit - emit formatted output based on format string and arguments
% man xo_attr
LIBXO(3) FreeBSD Library Functions Manual LIBXO(3)
NAME
xo_emit - emit formatted output based on format string and arguments
% man xo_create
LIBXO(3) FreeBSD Library Functions Manual LIBXO(3)
NAME
xo_emit - emit formatted output based on format string and arguments
