+Command Line Features
+---------------------
+
+-The user can choose to type in random mode where a random block is each 
+session is chosen from selected lesson.
+-And in standard mode, the user types chronologically as the lesson is in
+the lesson file. 
+-The user can chose to modify any lesson in the lesson file easily.
+-For a user who will not love to modify the lesson file, a my_own.txt file
+is available for the user to paste his text file he wants to type.
+
+NOTE: Text file should contain only ascii 7 bits characters. For this reason,
+user text may some times look absurd when contains extended ascii characters 
+since program has a function to ignore such characters.
+-User also can choose to receive a beep for any wrong character typed (may
+not work on all terminals)
+-Program has the ability to remember all past settings.
+-Terminal is manipulated so a user can erase characters right to the beginning
+of the session line(timing reset) For each wrong character erased, number of 
+errors is decremented by one.
+-User session timing starts only when he types a first character (wrong or 
+correct)
+-If the user erases to the beginning of the session, time is reset to zero
+and starts only as described above.
+-The last line of each lesson session is marked blue, so user is aware and 
+can take time to review speed details befor estarting the following lesson.
