"What makes bibtex superior over Endnote and Citavi is, that Bibtex was invented by the UNIX Community. It is working on the command line. Before somebody can use Bibtex, he has to become a UNIX expert, which means he needs to be familar with the C programming language, the Linux kernel and textformatting tools like sed, grep and awk." **
I am not going to comment on the ramifications of the idea that a bibliographic reference should demand familiarity with grep.
*Which I can't talk about because it would derail my indignation.
