The old version of readesm was using a command-line interface to convert the tachograph data into html. If one wanted it shown in the browser, there was a script to convert the file, write it to a temporary directory, and then open that file in the browser. However, this approach turned out to be not portable at all.
There were other problems: readesm was using custom Makefiles, which apparently made compiling the source difficult. I was amazed to discover this wiki entry for fahrlinx, which contained information on how to install the windows version of readesm using wine. As the windows version at that time was cross-compiled in linux and lacked some features, readesm was clearly too difficult to compile.
Digital tachographs are a compulsory equipment for heavy trucks in the european union. The companies owning these trucks have to download the data at least once every 3 months.
Without dedicated hardware, this was so far not easily possible in linux, but my python script should make it possible to download the data with a serial cable with the right connector.
Update, March 2011: There is a new release of readesm, The description provided here no longer applies, the new readesm uses Qt and cmake. You can get the new release at the sourceforge project page and read the documentation here.
For several years now, new trucks sold in the European union are equipped with digital tachographs, that record the driving times and replace the older chart-based mechanical tachographs.
