]{foils} in the
images.tex images.tex file is substituted by the header
\documentclass[$FOILOPTIONS $FOILOPTIONS]{$FOILCLASS $FOILCLASS},
where the variables $FOILOPTIONS $FOILOPTIONS and $FOILCLASS $FOILCLASS can be set
in the configuration file (by default they are '10pt' and
'article' correspondingly).
A further variable $FOILHEADLEVEL $FOILHEADLEVEL holds the level of sectioning
at which a `foil' is to correspond; the default level is 4 (sub-section).
The LATEX style file foilhtml.sty foilhtml.sty in the texinputs/ texinputs/ directory provides some additional features for FoilTeX. It implements structural markup commands like \section, \tableofcontents for foils. See the directory docs/foilhtml/ docs/foilhtml/ for the details.
