I am the developer of lcrt, In document of help, I make a detail description, I copy it to here:
(1) If you are a system administrator of unix/linux server, you can use lcrt, it can save your
session information, such as hostname, username and password(if you choose save password).So in
next time you connect to the server, you can't need to enter username and password. I think this
can be useful if you need login remote server hundred time every day.
(2) If you are a software engineer in embedded field, you may debug your software in embedded
device, and you should open several connection to look different result, so you can use lcrt to
clone as many connected session as you can. lcrt have some useful keyboard shortcut to clone,
close, move, and switch a session. As you known gnome-terminal is a popular terminal, so I use the
same keyboard shortcut to management session, such as CTRL+SHIFT+T to clone a session, ALT+1, ALT+2
to switch a session.
In short, there are two main function:
(1) auto save your connection information so that can auto login remote server next time.
(2) easy to clone a connected session, so you can open as many connection as you can.
