The System Browser provides an intuitive graphical way to examine and operate on systems and their members.
For example, the operation outlined in 26.2 A brief introduction to systems would be performed by the System Browser menu commands Systems > Compilation options > Force followed by Systems > Compile.
To create a System Browser, choose Tools > System Browser or press 
in the Podium. Alternatively, choose File > Browse Parent System from any appropriate tool in the environment or execute Alt+X Describe System in an editor, to display the parent system for the selected or current file in the System Browser. See 3.6 Operating on files for details.
In order to browse a system, first ensure it is defined. To define a system, load the Lisp source code containing the defsystem form into the Lisp image. For instance, open the file in an Editor and choose File > Load. Alternatively, choose File > Load... from the System Browser and choose a file to load in the dialog that appears.
