How to register HCatlog Library as part of pig script file

[mahender bigdata]

Hi,
We would like to make use of HCatlog table in our PIG Script file, 
Currently we are opening the PIG Command with -UseHCatlog option for 
registering or loading HCatlog library. Is there a way in PIG script to 
register HCatlog jar files
and execute directly on pig command prompt directly without any 
parameter options. Is this achievable ?
