Editing Groups

Then define and enter the groups of the module.  --  Next 

• Move to the group window and create a new group with <Alt+F2>. Enter the group's name and press <F2> for an additional description in the group text pane.
• Holon encourages top-down design. Sketch the program's structure with modules and groups.
• You can later rearrange the structure with ease. No messing around with source files.
