Well, about this, you can read related things, here is the original
repo: https://github.com/stardiviner/ob-clojure-literate. In the README,
I describe my motivation.

Before CIDER added "sesman" session manager, CIDER was not able to
manage sessions easily. But ob-clojure need a session. So I created it,
then I added some thing that I need for Clojure literate programming in
Org Mode.

About this extra library, here is what I think, keep it for a while,
until no one or very rare use it, I will remove it from Org Mode
contrib. Until now, no one except you asked me about what it is.

BTW, I migrated some features into core/ob-clojure.el already, like
session initialization. Specify session.

Here is the list I collate right now.

- [X] auto start REPL if necessary
  - [X] It's taken by CIDER sesman [Commit 2c5df17ed]
- [X] use default session
  - [X] It's taken by CIDER sesman, now can easily switch session.
- [ ] specify session in header argument :session, Org Babel has =[C-c C-v C-j]=
  by default.
  - [ ] provide interactive completion candidates of CIDER REPL connections
- [X] initiate session =[C-c C-v z]= [Commit 4456dc880]
  - [X] CIDER use sesman to manage REPL session now.
- [ ] support ob-core.el switch to corresponding session REPL buffer =[C-c C-v 
z]=
- [X] dynamic clojure ns [Commit d7e12d1df]
  - [X] implemented with ~:ns~ header argument [Commit d7e12d1df]
- [X] generate plot image in specific directory
  - [X] pass dir as variable into Clojure code
- [X] org babel support graphics image file link as result [Commit b088389c6]
  - [X] I add this header argument value in commit already. [Commit 296b0de4e]

If you want to read ob-clojure-literate.el source code, I suggest you
read one commit by one. It will be much clear. You can search my name
"stardiviner" and filter commits with "ob-clojure,ob-clojure-literate"
in log.

Hope this will help you, Regards.
