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
--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 searched in directories on Windows or Linux that have been
searched with fontconfig.
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 the fontconfig locations or, in Mac OS X, searching the
default system 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-cache/generic/names."
