+# This AWK script reads the output of testfixture when compiled for memory
+# debugging.  It generates SQL commands that can be fed into an sqlite 
+# instance to determine what memory is never freed.  A typical usage would
+# be as follows:
+#
+#     make -f memleak.mk fulltest 2>mem.out
+#     awk -f ../sqlite/tool/memleak2.awk mem.out | ./sqlite :memory:
+#
+# The job performed by this script is the same as that done by memleak.awk.
+# The difference is that this script uses much less memory when the size
+# of the mem.out file is huge.
