In org-publish-project-alist, i have HTML publishing projects which
should be published to different target directories depending on e.g.
where emacs is running (which i determine in my init files using the MAC
address of the default GW, the name the machine, ...).

Here is an example: At home, i publish to a local directory
(:publishing-directory "~/tmp/publish-test") but at work i would like to
publish directly to a webserver (:publishing-directory
"/plinkx:doxydoc:~/public_html/publish-test" - this is on w32, using
tramps PuTTY/plink). To avoid having to change the definition of the
publishing project when i change locations i would like to construct the
actual value of :publishing-directory by calling a function:

         ("publishing-dir-test"
         :base-directory "~/Documents/Work/RS"
         :recursive t
         :base-extension "org"
         :exclude-tags ("intern")
         :publishing-directory '(expand-file-name "publish-test" 
kt:org-default-publishing-dir)
         :publishing-function org-publish-org-to-html)

Depending on the location i'm in, 'kt:org-default-publishing-dir' would
be set to either "~/tmp" or "/plinkx:doxydoc:~/public_html". Without the
patch, the example above does not work as the value of
:publishing-directory does not get evaluated.

Thanks for the hint. I've attached a revised version of the patch which
includes a changelog/commit msg - i hope that works for you.

Publish: allow dynamic construction of the publish destination.

* org-publish.el (org-publish-file): Added 'eval'ing the value of the
 :publishing-directory property before using it as destination of the
 publishing project. This allows to construct the publish destination
 directory dynamically at run-time using the return value of a
 function.
