# all (default)
#   Create all the necessary directories, javascript, css, etc.
#
# prod
#   Create static assets for production (v3 only).
#
# 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.
#
# 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.
