Using sp (simple project) you can goto and execute individual lines

Simple ProjectNoun sphelp has information on Simple Project utilities.

Using JHS locally, you might prefer desktop tools rather than the apps
provided by JHS. For example, your desktop editor (notepad, gedit,
emacs,..), OS file mangager (windows explorer, finder, ...), and grep might
be better than JHS jijs, jfile, and jfif.

SP utilities make it easier to use your desktop tools.

   sphelp
