# ALGO :
# this script use an $op to know what to do.
# if $op is empty or none of the above values,
#	- the default screen is build (with all records, or filtered datas).
#	- the   user can clic on add, modify or delete record.
# if $op=add_form
#	- if primkey exists, this is a modification,so we read the $primkey record
#	- builds the add/modify form
# if $op=add_validate
#	- the user has just send datas, so we create/modify the record
# if $op=delete_form
#	- we show the record having primkey=$primkey and ask for deletion validation form
# if $op=delete_confirm
#	- we delete the record having primkey=$primkey
