DESCRIPTION
       The package ppoopp33dd::::uuddbb provides simple in memory databases which can be
       used in conjunction with the pop3 server core provided by  the  package
       ppoopp33dd. The databases will use the names of users as keys and associates
       passwords and storage references with them.

       Objects created by this package can be directly used in the authentica-
       tion  callback  of pop3 servers following the same interface as servers
       created by the package ppoopp33dd.


       ::::ppoopp33dd::::uuddbb::::nneeww ?dbName?
              This command creates a new database object  with  an  associated
              global Tcl command whose name is dbName.  The command ddbbNNaammee may
              be used to invoke various operations on the  database.   It  has
              the following general form:

       ddbbNNaammee option ?arg arg ...?
              Option and the args determine the exact behavior of the command.

       The following commands are possible for database objects:

       dbName ddeessttrrooyy
              Destroys the database object.

       dbName aadddd user pwd storage
              Add a new user or changes the data of an existing  user.  Stores
              password and storage reference for the given user.

       dbName rreemmoovvee user
              Removes the specified user from the database.

       dbName rreennaammee user newName
              Changes the name of the specified user to newName.

       dbName llooookkuupp user
              Searches  the database for the specified user and returns a two-
              element list containing the associated password and storage ref-
              erence,  in this order. Throws an error if the user could not be
              found. This is the interface as expected by  the  authentication
              callback of package ppoopp33dd.

       dbName eexxiissttss user
              Returns  true  if  the  specified user is known to the database,
              else false.

       dbName wwhhoo
              Returns a list of users known to the database.

       dbName ssaavvee ?file?
              Saves the contents of the database into the given file.  If  the
              file  is not specified the system will use the path last used in
              a call to dbName rreeaadd. The generated file can  be  read  by  the
              rreeaadd method.

       dbName rreeaadd file
              Reads the specified file and adds the contained user definitions
              to the database. As the file is actually ssoouurrccee'd a safe  inter-
              preter  is  employed  to  safeguard against malicious code. This
              interpreter knows the aadddd command for  adding  users  and  their
              associated  data  to  this  database.  This command has the same
              argument signature as the method aadddd. The path of  the  file  is
              remembered internally so that it can be used in the next call of
              dbName ssaavvee without an argument.
