# If any arguments (from 2 on) contain a ":", then different versions
# are blocked in different slots. (Unlisted slots get the version without
# a ":", if none, then all versions are blocked). The parameter is then of
# the form VERSION:SLOT.  Any VERSION of 0 means that no blocker will be
# added for that slot (or, if no slot, then for any unlisted slot).
# A parameter of the form :SLOT means to block all versions from that slot.
# If VERSION begins with "<", then "!<foo" will be used instead of "!<=foo".
# As a special case, if a parameter with slot "3.5" is passed, then that slot
# may also be blocked.

# "4.x", but nothing following slot "4.x"
