 JAGS is Just Another Gibbs Sampler -- a program for analysis of

 The functionality of JAGS is based on the BUGS program created by the
 MRC Biostatistics Unit (http://www.mrc-bsu.cam.ac.uk/). There is a short
 manual that describes the differences between JAGS and BUGS.
 
-The manual is installed as /usr/local/share/doc/jags/jags_user_manual.pdf.

 Some of the BUGS examples have been modified to run with JAGS, and have
