+%% This is file `epspdfconversion.sty',
+%%
+%%
+%% It is based on epstopdf.sty by Heiko Oberdiek and an attempt to use Siep
+%% Kroonenberg tools Epspdf  (http://tex.aanhet.net/epspdf/)
+%% "on the fly" in LaTeX
+%%
+%% Please send suggestions to daniel.becker@uni-rostock.de
+%% version history:
+%%
+%% ToDo: 
+%%
+%% 0.3: Heiko Oberdiek substantially improved the code. 
+%%      The kvoptions-package is now used for the implemention of options. 
+%%      See the documentation %%      for effects and additional features. 
+%% 0.2: the package is now simply based on epstopdf. This package essentially
+%%      defines \@namedef{Gin@rule@.eps}#1{{pdf}{.pdf}{`\conversioncommand #1}}
+%%      differently than epstopdf. The code has been cleaned up. Improvements of
+%%      documentation and additional warning about pdfminorversion....
+%% 0.1: first try
