 * Tests for the Date_Calc class

 * this file is a good thing.
 *
 * Can be run via CLI or a web server.
 *
 * This test senses whether it is from an installation of PEAR::Date or if
 * it's from CVS or a .tar file.  If it's an installed version, use the
 * installed version of Date_Calc.  Otherwise, use the local development
 * copy of Date_Calc.
