File cases.txt

This directory contains input and output files for 29 test cases for
MODFLOW-2000 (Harbaugh and others, 2000; Hill and others, 2000).  This file
briefly describes each test case.  For each test case, the name of the name
file is the name of the test case followed by a period and the extension
"nam".  All files for a given test case share the test-case name as a common
filename base.
