" The `pslatex` and `pstex` drivers generate output for further processing by",
" LaTeX and TeX, respectively. Figures generated by `pstex` can be included",

" Syntax:",
" set terminal pslatex | |pstex {<color>} {<dashed>} {<rotate>}",
" {auxfile} {<font_size>}",
"",
" <color> is either `color` or `monochrome`. <rotate> is either `rotate` or",
" `norotate` and determines if the y-axis label is rotated. <font_size> is",
" used to scale the font from its usual size.",
"",
" If `auxfile` is specified, it directs the driver to put the PostScript",
" commands into an auxiliary file instead of directly into the LaTeX file.",
" This is useful if your pictures are large enough that dvips cannot handle",
" them. The name of the auxiliary PostScript file is derived from the name of",
" the TeX file given on the `set output` command; it is determined by replacing",
" the trailing `.tex` (actually just the final extent in the file name) with",
" `.ps` in the output file name, or, if the TeX file has no extension, `.ps`",
" is appended. Remember to close the file before leaving `gnuplot`.",
"",
" All drivers for LaTeX offer a special way of controlling text positioning:",
" If any text string begins with '{', you also need to include a '}' at the",
" end of the text, and the whole text will be centered both horizontally",
" and vertically by LaTeX. --- If the text string begins with '[', you need",
" to continue it with: a position specification (up to two out of t,b,l,r),",
" ']{', the text itself, and finally, '}'. The text itself may be anything",
" LaTeX can typeset as an LR-box. \\rule{}{}'s may help for best positioning.",
"",
" Examples:",
" set term pslatex monochrome dashed rotate # set to defaults",
" To write the PostScript commands into the file \"foo.ps\":",
" set term pslatex auxfile",
" set output \"foo.tex\"; plot ...: set output",
" About label positioning:",
" Use gnuplot defaults (mostly sensible, but sometimes not really best):",
" set title '\\LaTeX\\ -- $ \\gamma $'",
" Force centering both horizontally and vertically:",
" set label '{\\LaTeX\\ -- $ \\gamma $}' at 0,0",
" Specify own positioning (top here):",
" set xlabel '[t]{\\LaTeX\\ -- $ \\gamma $}'",
" The other label -- account for long ticlabels:",
" set ylabel '[r]{\\LaTeX\\ -- $ \\gamma $\\rule{7mm}{0pt}'",
"",
" Linewidths and pointsizes may be changed with `set linestyle`."
