* If you check out the sources from Git, use this to regenerate things:

  autoreconf -isf
  ./configure --enable-maintainer-mode ...

* The release version is in configure.ac!

* Important: add AC_REPLACE_FUNCS sources to EXTRA_DIST!

* do "make distcheck" before you release

* do "make lsm" to get the lsm file.

* Only use ln_log for LNLOG_SERR severity. The verbosity scheme does not
  fit otherwise.

* OpenSource Docbook conversion is a mess.
  Several solutions are conceivable:
  - XSL sheet -> FO -> XEP -> PDF          best result, costly
  - XSL sheet -> FO -> FOP -> PDF          works
  - DSSSL sheet -> Jade -> JadeTeX -> PDF  works
  - XSL sheet -> PassiveTeX -> PDF         doesn't work at the moment (2005-03)
