Each subdirectory contains one of the domain and all of the
tests for that domain used in the AIPS-2002 planning competion that
TLPlan won. 

Just enter the directory and execute

tlplan runall.tlp

This will produce all of the solutions. Most of the directories also 
have a <domain-name>.csv file. This is the statistics file for tlplan
run on the problems on a 2.2 GHz machine.
