-# 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.
