+# Purpose:
+#    Simple search with Perl for a pattern in some file.
+#
+#    The advantages compared to thinkable auxiliary constructs using the
+#    mysqltest language and SQL are:
+#    1. We do not need a running MySQL server.
+#    2. SQL causes "noise" during debugging and increases the size of logs.
+#       Perl code does not disturb at all.
+#
+#    The environment variables SEARCH_FILE and SEARCH_PATTERN must be set
+#    before sourcing this routine.
+#
+#    In case of
+#    - SEARCH_FILE and/or SEARCH_PATTERN is not set
+#    - SEARCH_FILE cannot be opened
+#    - SEARCH_FILE does not contain SEARCH_PATTERN
+#    the test will abort immediate.
+#    MTR will report something like
+#    ....
+#    worker[1] Using MTR_BUILD_THREAD 300, with reserved ports 13000..13009
+#    main.1st                                 [ pass ]      3
+#    innodb.innodb_page_size                  [ fail ]
+#            Test ended at 2011-11-11 18:15:58
