The format of section heads may be controlled by the command\mysection{<sec>}{<style>}{<preface>}
Here <sec> is the section level — section, subsection, etc. The style in which the section is to be set is
specified by <style>; e.g., \large\sf. The argument
<preface> is the text to be set before the text of the section
head — usually \thesection and some punctuation. For example
the section heads in this document were produced by the commands.\mysection{section}{\large\bf}{\thesection.~}
\mysection{subsection}{\normalsize\bf}{\thesubsection.~}
\mysection{subsubsection}{\normalsize\bf}{\thesubsubsection.~}
\mysection{paragraph}{\normalsize\bf}{\theparagraph.}
\mysection{subparagraph}{\normalsize\bf}{\thesubparagraph.}
These are the default for jeep.sty.
