# all (default)
#   Same as `make dirs js icons skins robots`
#
# dirs
#   Creates the required directories not present in git
#
# js
#   Generates the Javascript code
#
# icons
#   Generates the CSS icon sprites
#
# 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.
#
# chmod-autoupdate
#   As chmod, but also chmods all files that may need to be updated from a
#   normal 'make' run. Should be used when the regen_static option is enabled
#   and the http process is run from a different user.
#
# multi-start, multi-stop, multi-restart:
#   Start/stop/restart the Multi daemon. Provided for convenience, a proper initscript
#   probably makes more sense.
#
# NOTE: This Makefile has only been tested using a recent version of GNU make
#   in a relatively up-to-date Arch/Gentoo Linux environment, and may not work in
#   other environments. Patches to improve the portability are always welcome.
