Usage: %s [OPTION]...
Rebuild the LuaTeX font database.
Valid options:
-d --database-dir=DIRECTORY install the database in the specified directory
-f --force force re-indexing all fonts
-q --quiet don't output anything
-v --verbose=LEVEL be more verbose (print the searched directories)
-vv print the loaded fonts
-vvv print all steps of directory searching
--fc-cache run fc-cache before updating database
--sys install the database system-wide
(default is only for the current user)
-V --version print version and exit
-h --help print this message
Fonts are found on Windows or Linux with fontconfig (i.e., using fc-list).
On Mac OS X, only fonts located in the following standard font locations are
included in the font database:
~/Library/Fonts /Library/Fonts
/System/Library/Fonts /Network/Library/Fonts
In particular, fonts installed in other locations with "Font Book" will not
be available.
Rather than using fontconfig or, in Mac OS X, searching the default font
locations, you may specify where fonts are located by setting the OSFONTDIR
environment variable. Doing so will override the use of fontconfig or
scanning the system font locations. If you wish to continue to include them
while also including other font locations, simply include them in the list.
For example (using a bash shell),
export OSFONTDIR='/path/to/other/fonts:/Users/will/Library/Fonts:...'
The output database file is named otfl-fonts.lua. By default it is placed
in $TEXMFVAR/luatex/generic/luaotfload/names.
