-# render_getConfigOption.sh -- This function standardizes the way
-# action values are retrived from pre-rendition configuration files.
-# Use this function whenever you need to retrive action values from
-# pre-rendition configuration script.
-#
-# Usage: VAR=$(render_getConfigOption "ACTION" "FIELD")
-#
-# VAR is the name of the variable where we store the option named
-# returned by render_getConfigOption. 
-#
-# ACTION is the string definition set in the pre-rendition
-# configuration script that holds the action name and its options
-# fields.
-#
-# FIELD is the field number in the action string we want to retrive
-# option from. By default options start from third field on. The first
-# field is reserved for the action type (i.e., POST or LAST), and the
-# second field is reserved for the action itself (e.g., convertPngTo,
-# renderSyslinux, renderKsplash, etc.).
