I maintain my blog with org mode. One of my preparation functions
generates an atom feed for my blog. This function uses
`org-publish-get-base-files' to get the path to the org source files
corresponding to my blog posts. In order to supply the PROJECT argument
of `org-publish-get-base-files', I need to know the project-plist.

In general, the preparation function having access to project-plist is a
very useful feature. Many a time, it avoids the need to get the plist
indirectly by accessing org-publish-project-alist or by some other means.
