Use the syntax:
include { path path ... }
For example, the following lines source in the file /users/ellen/mymenu:
include { /users/ellen/mymenu }
Include statements are useful for providing additional functionality without copying the entire configuration file. For example, a user might want to create a new key binding without having to administer the entire configuration file. The user can create a file HomeDirectory/.dt/dtwmrc with this content:
include { /etc/dt/config/C/sys.dtwmrc } Keys DtKeyBindings { Alt<Key>F5 root f.menu Applications
}
Menu Applications { "GraphicsApp" f.exec "/usr/bin/GraphicsApp/GApp" ... }
