+# This script is part of ypserv package.
+# We need to pass all environment variables set in /etc/sysconfig/yppasswdd 
+# to rpc.yppasswdd daemon, but only if they are not empty. However, this 
+# simple logic is not supported by systemd. 
+# This script wraps the main binary, prepares YPPASSWDD_ARGS variable 
+# to include all necessary variables (ETCDIR, PASSWDFILE and SHADOWFILE)
+# and passes this variable to daemon. 
+# The script ensures, that the rpc.yppasswdd arguments are not used in case 
+# the appropriate environment variables are empty.
