For these programs to run well, you need to install SPost first as the grcompare commands use some low 
utility programs from SPost ({net search SPost}) written for Stata 9 (spost9_ado).  While installing SPost, 
you need to be aware that there could be variations across different versions. More recent versions of SPost may 
work well with grcompare, but the author of grcompare has not systematically tested yet.  You are encouraged to 
cite our work if you use this suite of commands in your own works:
