org-publish-project-alist Publishing
is configured almost entirely through setting the value of one
variable, called org-publish-project-alist. Each
element of the list configures one project, and may be in one of
the two following forms:
("project-name" :property value :property value ...)
i.e. a well-formed property list with alternating keys and values
or
("project-name" :components ("project-name" "project-name" ...))
In both cases, projects are configured by specifying property
values. A project defines the set of files that will be
published, as well as the publishing configuration to use when
publishing those files. When a project takes the second form
listed above, the individual members of the
:components property are taken to be sub-projects,
which group together files requiring different publishing
options. When you publish such a “meta-project”, all
the components will also be published, in the sequence given.
