+# Data is supposed to be in file.txt in the following format:
+# host001_1;user001_1;password001_1;host001_2;user001_2;password001_2;
+# ...
+# Separator is character semi-colon ";" it can be changed by any character changing IFS=';' 
+# in the while loop below.
+# # Each line contains 6 columns, columns are parameter values for 
+# --host1 --user1 --password1 --host2 --user2 --password2
+# and a trailing empty fake column to avoid CR LF part going 
+# in the 6th parameter password2. Don't forget the last semicolon.
+#
+# You can add extra options after the variable "$@" 
+# Use character backslash \ at the end of each supplementary line, except for the last one.
+# You can also pass extra options via the parameters of this script since
+# they will be in "$@"
+
+# The credentials filename "file.txt" used for the loop can be renamed 
+# by changing "file.txt" below.
+
+# The part 'echo {1} | egrep "^#" > /dev/null ||' is just there to skip commented lines in file.txt
+# It can be removed if there is no comment lines in file.txt
