Initial Package Development
David Developer writes a piece of software used to do knowledge management (km) for the OpenACS. He distributes his data model, procedure code, UI pages, and his documentation according to the APM specification. He splits the documentation and the code into sub-packages, and creates a KM installation-chain to install both with the APM developer -UI. Noting that his software was built with Patricia -Programmer's Super Widget toolkit, he specifies that as a +UI. Noting that his software was built with Patricia +Programmer's Super Widget toolkit, he specifies that as a dependency. Moreover, since this package is capable of being used at the sub-site level, David configures this option in the package. When the package development is complete, David uses the APM developer UI to construct a distribution file. He assigns it a version number, 1.0, and makes the package -available for download at the OpenACS package repository.
