Changes

After installing new fonts, the font datamase database must be rebuilt for LuaTeX to access them. In current versions of Mark IV (earlier than July 2008) this is automatically done whenever a named font cannot be found. You only have to do the reload manually when you have installed updates to already installed fonts that cause the font and/or file names to change. This normally only happens for fonts that are still in development like [[TeX Gyre]] and [[Latin Modern]].

Alternatively, you can get turn off the automatic rebuild of the database to be automatically rebuilt when needed -- that is, on 'font not found' errors. To do so, set by setting either of

to "yesno".
