+% \section{Maintaining the font database}
+% \label{sec:fontdb}
+%
+% As introduced in the previous section, \textsf{luaotfload} uses a database
+% to keep track of fonts available to \LuaTeX. Using this database, fonts can
+% be loaded by font name as well as filename.
+%
+% This font database must be maintained as you add (and remove) fonts to your
+% system. To update the database, run the script |mkluatexfontdb.lua| that is
+% included with this package. If you have not run it before, it may take quite
+% some time to process every font on your computer. Subsequent runs to update
+% the database will be quite fast, however.
+%
+% In \TeX~Live~2010, there will be a button in the \TeX~Live package manager
+% to run |mkluatexfontdb.lua|.
+%
+% The script will parse standard places for fonts in your system to build the
+% font database. On Windows and Linus, it will use |fc-list| to find the
+% fonts; on Mac~OS~X, it will search in the standard font locations
+% |~/Library/Fonts|, |/Library/Fonts|, |/System/Library/Fonts|, and
+% |/Network/Library/Fonts|,
+%
+% If you do not wish the script to locate fonts automatically but would rather
+% specify the exact locations in which to find your fonts, set the |OSFONTDIR|
+% environment variable instead. When this variable is set, the script will
+% only search in those directories.
+%
+% |mkluatexfontdb.lua --help| provides a brief summary of the functionality of
+% the script and includes some advanced options that we have not mentioned
+% here.
