Creating the installable package

1. Create the following files for the installable package:

   
   prototype

   Contains the package content definition. See prototype file.

   
   pkginfo

   Contains the package info. See pkginfo file.

   
   depend

   contains the package dependencies. See depend file.

   
   postinstall

   writes the private file created above to the end of the /usr/lib/scoadmin/printer/model.stz file, and adds any new filters and any new terminfo definitions to the lp system. See postinstall file.

   Any scripting language can be used. There are advantages to using OSA VTCL; see Developing Visual Tcl applications.

   
   preremove

   removes the items installed by the postinstall script. See preremove file.

2. Create the installable package. This example assumes that:

   • The files described above have been created in the /home/pkgbuild/src directory.

   • The created packages will be put into the /home/pkgbuild/pkgs directory.

   • The new printer is called ``oklaster''.

   Create the package:

      pkgmk -o -f /home/pkgbuild/src/prototype -d /home/pkgbuild/pkgs oklaser
   

   Convert the package to a bit stream:

      pkgtrans -s /home/pkgbuild/pkgs "-" all >/home/pkgbuild/pkgs/oklaser.pkg
   

3. The oklaster.pkg file is ready for distribution. It can be put on a download web page or put onto issue media such as a floppy disk.
