This is a DEMO version of the SuperMemo 6 Professional
       program. You are allowed to use it for one month after
       the initialization of a database. 
       Passwords will not be required for at least one
       month after the initialization of each database, which
       means that you will be able to safely work with each SuperMemo
       database, created by means of this program version, for
       one month since you create it or trasform it to an intact
       form using TRANSF6.EXE. Not inputing the correct password
       when requested as well as any other abnormal termination of the
       program may destroy the integrity of the database being used.

       You may copy and distribute verbatim copies of this demo
       version of the SuperMemo 6 Professional  files
       provided that you keep intact all copyright
       notices and give to any other recipients of this program a

       disclaimer. You may not disassemble or modify the software
