+# Proc [do_matchinfo_test] is used to test the FTSX matchinfo() function.
+#
+# The first argument - $tn - is a test identifier. This may be either a
+# full identifier (i.e. "fts3matchinfo-1.1") or, if global var $testprefix
+# is set, just the numeric component (i.e. "1.1").
+#
+# The second argument is the name of an FTSX table. The third is the 
+# full text of a WHERE/MATCH expression to query the table for 
+# (i.e. "t1 MATCH 'abc'"). The final argument - $results - should be a
+# key-value list (serialized array) with matchinfo() format specifiers
+# as keys, and the results of executing the statement:
+#
+#   SELECT matchinfo($tbl, '$key') FROM $tbl WHERE $expr
+#
+# For example:
+#
+#   CREATE VIRTUAL TABLE t1 USING fts4;
+#   INSERT INTO t1 VALUES('abc');
+#   INSERT INTO t1 VALUES('def');
+#   INSERT INTO t1 VALUES('abc abc');
+#
+#   do_matchinfo_test 1.1 t1 "t1 MATCH 'abc'" {
+#     n {3 3}
+#     p {1 1}
+#     c {1 1}
+#     x {{1 3 2} {2 3 2}}
+#   }
+#
+# If the $results list contains keys mapped to "-" instead of a matchinfo()
+# result, then this command computes the expected results based on other
+# mappings to test the matchinfo() function. For example, the command above
+# could be changed to:
+#
+#   do_matchinfo_test 1.1 t1 "t1 MATCH 'abc'" {
+#     n {3 3} p {1 1} c {1 1} x {{1 3 2} {2 3 2}}
+#     pcx -
+#   }
+#
+# And this command would compute the expected results for matchinfo(t1, 'pcx')
+# based on the results of matchinfo(t1, 'p'), matchinfo(t1, 'c') and 
+# matchinfo(t1, 'x') in order to test 'pcx'.
