+Rebuild ls-R filename databases used by TeX. If one or more arguments
+DIRS are given, these are used as the directories in which to build
+ls-R. Else all directories in the search path for ls-R files
+(\$TEXMFDBS) are used.
+
+Options:
+ --dry-run do not actually update anything
+ --help display this help and exit
+ --quiet cancel --verbose
+ --silent same as --quiet
+ --verbose explain what is being done
+ --version output version information and exit
+
+If standard input is a terminal, --verbose is on by default.
+
+For more information, see the \`Filename database' section of
+Kpathsea manual available at http://tug.org/kpathsea.
