Out now: serienbrief 0.2.4

I just uploaded the new bugfix release 0.2.4 of serienbrief, the LaTeX form letter generator.

There have been problems with complex documents, probably caused by colliding aux files. This has been fixed by using different temp files for each form letter.

Additionally, the command line option --repeat has been introduced so that LaTeX can be called multiple times to e. g. get cross-references right.
