True, but my patch is not about doing away with `org-ditaa-jar-path'
variable, it is about broadening the definition of "standard location"
so to speak.

Right now, being defined relatively to ob-ditaa.el, aforementioned
standard location is at the mercy of what/whoever that is responsible
for deciding where all the stuff belonging to emacs and org-mode goes.

IMHO, that floating filesystem location is hardly more standard than the
place where Distro X's package management tools place ditta.jar
after installation.

I understand where you're coming from. True, it is not possible to
handle all obscure and arcane cases, that's what all these variables are
for, but I don't think that a situation where user installs ditaa and
later emacs, both via the package management system and find themselves
unable to draw awesome ditaa diagrams without looking a variable up in
documentation, adding appropriate code to his configuration file and
hitting C-x C-e is some sort of a fringe use-case. If only
myself and maybe another person has ever hit that roadblock, than I
agree, it is not worth adding any additional code, and I rest my case.

Thanks for the tip, didn't know about that particular command.
I usually use combination of C-h v and good old
M-x download-the-source-and-look-how-the-thing-works :-).
