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 Smalltalk for OS/2, VisualAge Smalltalk for Linux, VisualAge Smalltalk for Windows, VisualAge Smalltalk for AIX, VisualAge Smalltalk for Sun Solaris, or VisualAge Smalltalk for HP-UX so consider using a utility that supports multiple platforms.
