+// This program finds all of the tokudb status dictionary files and deletes the FRM from them.
+//
+// Requirements:
+// The directory containing the tokudb environment is passed as a parameter.
+// Needs the log*.tokulog* crash recovery log files.
+// Needs a clean shutdown in the recovery log.
+// Needs the tokudb.* metadata files.
+//
+// Effects:
+// Deletes the FRM row from all of the tokudb status dictionaries.
+// Creates a new crash recovery log.
