+#
+# Comments on usage from the email we received:
+# I showed a friend the following script. He said I should submit it for
+# inclusion in openldap, because it might useful for others.
+#
+# The attached perl script, when used like
+#
+# ldapsearch | ldiftopasswd
+#
+# will automatically:
+#
+# 1. create /etc/passwd, /etc/shadow, /etc/group, and /etc/gshadow
+#
+# 2. append /etc/passwd.top, /etc/shadow.top, /etc/group.top, and /etc/gshadow.top to respective files.
+#
+# 3. use data from ldap to create the files (note: gshadow isn't really
+# supported, because I don't use it, nor could I find any
+# documentation. Adding support for other files should be easy).
+#
+# (of course you need access to all fields including the password field
+# for this, so use correct parameters to ldapsearch).
+#
+# This could be useful for instance on laptop computers where you don't
+# want to run a slave slapd server for some reason (perhaps memory
+# constraints).
