To build the distribution diskettes and to automate the steps described above, you can write your own program, or you can use one of many commercially available installation utilities. These utilities can greatly reduce the number of steps required to create distribution diskettes. Keep in mind that your parts might be installed on VisualAge for OS/2, VisualAge for Windows, VisualAge for AIX, VisualAge for Sun Solaris, or VisualAge for HP-UX so consider using a utility that supports multiple platforms.
