TSORT(1)            UNIX Programmer's Manual             TSORT(1)

NAME
     tsort - troff sort program

SYNTAX
     tsort [file ... ]

DESCRIPTION
     _t_r_o_f_f(1) produces phototypesetter ouput which is simulated
     on the Versatec by _v_c_a_t(1). _v_c_a_t cannot buffer up many
     typesetter commands before it must flush its Versatec
     buffer.  Thus documents containing large backwards motions
     will be typeset wrong.  Large backwards motions are produced
     by _e_q_n(1), multiple columning, and line drawing commands.
     Thus the need for _t_s_o_r_t, which sorts out all the reverse
     motions in a _t_r_o_f_f input stream.  If no file arguments are
     given _t_s_o_r_t reads it's standard input.  A typical usage is:
           troff -t files | tsort | vcat

SEE ALSO
     troff(1), troff(5), eqn(1), vcat(1), Troff manual.

DIAGNOSTICS
     Cannot open input file.
     Cannot alloc.

BUGS
     _t_s_o_r_t has a limit of 12 inches of reverse line motion.  Its
     troff code generator leaves something to be desired.
