+====== Nice Scripts ======
+===== Welcome to Shell Scripting! =====
+==== Parsing Configs ====
+The file.csv file content is :
+<file>
+user0001;password0001;user0002;password0002
+user0011;password0011;user0012;password0012 ...
+</file>
+And the shell program is just :
+  { while IFS=';' read u1 p1 u2 p2; do imapsync --user1 $u1 --password1
+  $p1 --user2 $u2 --password2 $p2 ... done ; } < file.csv
+==== Bash Readarray ====
+Better than the above ''while read'' loop is the use of Bash's builtin
+''readarray'' as it allows to avoid spawning a sub-shell and therefore variable
+assignments from inside the loop work.
