# ------------------------------------
#
# Project:	Noid
#
# Name:		noid7.t
#
# Function:	To test the noid command.
#
# What Is Tested:
#		Create minter with template de, for 290 identifiers.
#		Mint 2 noids.
#		Bind an element/value to the first one using the ":"
#			option.
#		Bind an element/value, with the element length greater
#			than 1,500 characters, and the value being
#			10 lines, to the second one using the ":-" option.
#		Fetch the bindings and check that they are correct.
#
# Command line parameters:  none.
