# (If you change or delete the word `original' on the previous line,

#
# Suitable for calling from cron, as in:

# Originally written as `texhash' by Thomas Esser, Okt., 1994.

progname=`echo $0 | sed 's%.*/%%'`
usage="Usage: $progname [OPTION]... [DIR]...
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.
