About Info*Engine Packages
A package is a set of files to be delivered into your task root, and (if necessary) associated LDAP infrastructure entries required for an application to function. Utilizing packages allows these files and directory entries to be installed, updated, and uninstalled from a system in sets rather than individually. Using packages also greatly simplifies the installation and maintenance of federated applications requiring updates to the LDAP.
Task packages may contain any files to be delivered into your task root, most commonly XML tasks, XSL style sheets, and tag library descriptor files. Task package filenames end with the extension .ptctar.
