From Deepak Garg:

Last week we formed two teams to deal with two separate tasks. The first 
team has successfully implemented a unification module, complete with 
parameter dependencies. The other team spent a lot of time this week 
figuring out the details of rule generation, creation of initial 
sequents and dependence of variables on parameters and parameter 
variables. At today's meeting we came to a number of conclusions 
regarding these issues and we are now in a position to implement these.
