# all (default)
#   Same as `make dirs js skins robots`
#
# dirs
# 	Creates the required directories not present in git
#
# js
# 	Generates the Javascript code
#
# skins
# 	Generates the CSS code
#
# robots
# 	Ensures that www/robots.txt and static/robots.txt exist. Can be modified to
# 	suit your needs.
#
# chmod
# 	For when the http process is run from a different user than the files are
# 	chown'ed to. chmods all files and directories written to from vndb.pl.
# 	(including the stylesheets and javascript code, so these can be auto-updated)
#
# chmod-tladmin
# 	The TransAdmin plugin also needs write access to some files
#
# multi-start, multi-stop, multi-restart:
# 	Start/stop/restart the Multi daemon. Provided for convenience, a proper initscript
# 	probably makes more sense.
#
#	sql-import
#		Imports util/sql/all.sql into your (presumably empty) database
#
#	update-<version>
#		Updates all non-versioned items from the version before to <version>.
#
# NOTE: This Makefile has only been tested using a recent version of GNU make
#   in a relatively up-to-date Arch Linux environment, and may not work in other
#   environments. Patches to improve the portability are always welcome.
