 Q:
 What is PWM/Pi
 A:
 PWM/Pi is the platform-independend version of PwManager 1.0.1, written by
 Michael Buesch and the PwManager Team (http://passwordmanager.sourceforge.net)

 PWM/Pi is the platform-independend version of PWManager and it

 *************************************************************************
 Q:
 Can I exchange the password files from PWM/Pi and PwManager
 A:
 The password files of PWM/Pi can not be exchanged with all versions up
 to 1.0.1 of PwManager.
 However, Michael will integrate our changes into a PwManager release
 1.1, and the password files of that release will then be interchangable
 with PWM/Pi
-

+*************************************************************************
+Q:
+Does Export/Import keep sync information in place
+A:
+Exporting data from PwManager removes all sync related information 
+(Meta information) from the data. Because of that, a subsequent import
+results in "new" entries that will be handled as new entries when
+syncing them with an existing password file.
+*************************************************************************
+Q:
+Can PWM/Pi sync categories?
+A:
+No. PWM/Pi does not sync categories. It syncs all pw entries of the file
+without checking for the entries categories. 
+A sync operation does not move modified entries from one category to another.
+Only if the sync operation has to create a new pw entry, it checks for the
+existance of the category and creates it if not existent.
+*************************************************************************
+Q:
+Which crypto, hash and compress algorithm is applied to the remote file
+while syncing?
+A: The sync operation applies the local crypt, hash and compress algorithm   
+to both, the local and remote copy of the passwordfile and with thus
+overwrites the settings of the remote PwManager application.
