+# This little script runs a test program on a given (calendar) file and
+# compares the output to a reference file. All discrepancies are shown
+# to the user. Usage:
+# runtestcase.pl appname identifier testfile.ics
+# 'identifier' is used as a suffix to allow multiple tests on the same input
+# file during a test run.
+#
+# The application/script appname is required to take two arguments:
+# appname inputfile outputfile
+# where inputfile is the file to be used as input data, and the output of the
+# program will go to outputfile (=testfile.ics.identifier.out if called through
+# runtestcase.pl). That outputfile is then compared to the reference file
+# testfile.ics.ref.
