# Download slax-6.x.x.tar to the same directory as this script before running it
#       http://www.slax.org/get_slax.php

# You must be root to run this script.

# This uses the  "@@"  syntax in the way that JAR files use it.  That is,
# "@@"  signifies that the file being looked at resides *inside* of the
# given archive file.


# NOTE: unlike what another script implies
#       http://www.slax.org/forum.php?action=view&parentID=367
# httpfs is already INCLUDED in the stock initrd. (as of SLAX v6.1.2)
# So you don't need to remaster the initrd if that's what you're
# looking for.
