+** SQLite uses this code for testing only.  It is not a part of
+** the SQLite library.  This file implements two new TCL commands
+** "md5" and "md5file" that compute md5 checksums on arbitrary text
+** and on complete files.  These commands are used by the "testfixture"
+** program to help verify the correct operation of the SQLite library.
+**
+** The original use of these TCL commands was to test the ROLLBACK
+** feature of SQLite.  First compute the MD5-checksum of the database.
+** Then make some changes but rollback the changes rather than commit
+** them.  Compute a second MD5-checksum of the file and verify that the
+** two checksums are the same.  Such is the original use of this code.
+** New uses may have been added since this comment was written.
