This is to announce an updated version of the blockrand package has been
uploaded to CRAN.

The blockrand package is used for creating randomizations for clinical
trials or other studies where random assignments are made one at a time.
It implements the ideas of randomizing within blocks so that the numbers
of subjects in each group remain fairly balanced (but allows for
unbalanced blocks to make anticipation of future allocations more

It also includes a function to print randomization cards (creates a pdf
file) that can be put into envelopes for a study coordinator to use to
assign subjects to treatments.
