+# pwgrep v0.2 (c) 2009 by Dipl.-Inform. (FH) Paul C. Buetow
+# pwgrep helps you to manage all your passwords using GnuGP
+# for encryption and a versioning system (subversion by default)
+# for keeping track all changes of your password database. In
+# combination to GnuPG you should use the versioning system in
+# combination with SSL or SSH encryption.
+
+# If you are using a *BSD, you may edit the shebang line.
+#
+# Usage: 
+#  Searching for a database value: 
+#	./pwgrep.sh searchstring 
+#  Editing the database (same but without args): 
+#	./pwgrep.sh 
+# For more reasonable commands the following symlinks are recommended: 
+#	ln -s ~/svn/pwgrep/pwgrep.sh ~/bin/pwgrep
+#	ln -s ~/svn/pwgrep/pwgrep.sh ~/bin/pwedit
+
+# You can overwrite the default values by setting env. variables
+# or by just editing this file.
