[Serusers] LCR Module : How to create the mySQL tables?

Hello List. I'm trying to use the LCR module submitted by Juha. I have a basic question. In the README file appears a description of the tables for the LCR module. How can i define this tables in my mysql database? i mean which is the type (VARCHAR?, INT?, etc. )for each column? I only found this in the mailing list : # # Table structure for table 'gw' # CREATE TABLE gw ( gw_name VARCHAR(128) NOT NULL, ip_addr INT UNSIGNED NOT NULL, port SMALLINT UNSIGNED, grp_id INT UNSIGNED NOT NULL, PRIMARY KEY (gw_name), KEY (grp_id) ) $TABLE_TYPE; But how is the format for the lcr and gw_grp tables? I appreciate any help, Thanks Ricardo
