Rem    NAME
Rem      utlxpls.sql - UTiLity eXPLain Serial plans
Rem
Rem    DESCRIPTION
Rem      script utility to display the explain plan of the last explain plan
Rem	 command. Do not display information related to Parallel Query
Rem
Rem    NOTES
Rem      Assume that the PLAN_TABLE table has been created. The script 
Rem	 utlxplan.sql should be used to create that table
Rem
Rem      To avoid lines from truncating or wrapping around:
Rem         'set charwidth 80' in svrmgrl
Rem	    'set linesize  80' in SQL*Plus
