Zahlavi a zapati v knize - reseni?

[Zbynek HOuska]

Dobry vecer,

tady jsem vytvoril neumely pokus, jenom to nejak pokulhava. Sazi to pouze 
leve zahlavi na vsech stranach a stezuje si na \nadpis #1. Poradi mi nekdo?
Zadne pocitani ani obsahy nepotrebuju, alespon pro zacatek. Staci mi to tak 
jak to je, jenom aby to fungovalo ....
Moje schopnosti na to nestaci.

Dekuji    Zbynek Houska

Tady je ten vytvor inspirovany tbn.tex:

%plovouci zahlavi
\def\nadpis#1{ \centerline}
\def\starthead{\global\headline=
	{\ifodd \pravezahlavi \else \levezahlavi \fi}}
\def\pravezahlavi{\hfil\nadpis#1 \hfil}
\def\levezahlavi{\hfil CÍL CESTY NEZNÁMÝ \hfil}
\def\kap#1 \par{\vfill\break
	\headline={\hfil\starthead}
	\hbox{}\nadpis#1}

Jeste prikladam castecny vypis z kniha.log:

You meant to type ## instead of #, right?
Or maybe a } was forgotten somewhere earlier, and things
are all screwed up? I'm going to assume that you meant ##.

Contemporary agriculture treats-Mother-Earth like a whore and rapes her.
All year round it scrapes away her skin and poisons it with artificial
fertilizer, for which a science is to be thanked that has lost all
conections with Nature.
