prepinac latex/pdflatex

[Tomas Davidek]

Dobry den,
   mam velky dokument, ktery potrebuji nekdy zpracovat latexem, jindy
pdflatexem. Abych nemusel menit dokument, nasel jsem kdysi nekde toto
reseni vlozene do hlavicky:
\newif\ifpdf
\ifx\pdfoutput\undefined
\pdffalse % we are not running PDFLaTeX
\else
\pdfoutput=1 % we are running PDFLaTeX
\pdftrue
\fi
% Then use your new variable \ifpdf
\ifpdf
\usepackage[pdftex]{graphicx}
\pdfcompresslevel=9
\DeclareGraphicsExtensions{.pdf} % {.jpg,.pdf,.mps,.png}
\else
\usepackage[dvips]{graphicx}
\DeclareGraphicsExtensions{.eps} % {,.ps,.bmp,.tif,.tiff,.tga}
\fi

Tohle velmi dobre fungovalo, dokud jsem pouzival tetex 2.0.2 (Debian
Sarge). Vystup z logu pri spusteni "latex tbpaper" vypadal:
-----------
This is TeX, Version 3.14159 (Web2C 7.4.5) (format=latex 2006.1.19)  10

Ovsem na notebooku jsem si nainstaloval vyssi distribuci (Debian Etch,
cili testing), kde je tetex-3.0.15 a kde vyse uvedena mantra uz
nefunguje. Vystup z logu pri spusteni "latex tbpaper" vypada takto:

Po blizsim zkoumani se ukazalo, ze prestoze prekladam latexem, tak je
zjevne splnena podminka  \ifpdf a proto se ocekava obrazek ve Formatu
PDF misto EPS.

Dotaz tedy zni: existuje nejaky jiny/lepsi zpusob, jak osetrit preklad
latex/pdflatex, fungujici v obou verzich ? Nebo je problem nekde v
konfiguraci tetexu ?

Diky predem za jakekoli info,

   zdravi
