Viewed over the USB cable:
/
Viewed from the command line:
/mnt/us/
So here shown as:
*/
*/extensions/<add-in name>/menu.json <<-- this file lists the association between menu label and script that performs the action
*/extensions/<add-in name>/config.xml <<-- configuration info for the menu, not for the add-in
*/extensions/<add-in name>/bin/*.sh <<-- the script(s) that perform the menu action
Rather than call that script with KUAL, copy it and call it with ;log runme
About the only thing you **might** have to do is add a:
cd /mnt/us/extensions/<add-in name> to the script (something that KUAL does, sets the current directory)
All of which is fully documented in the Wiki.
How to find the Wiki entry.
As usuall, we hide it behind some writing to be read:
First post of the KUAL release thread, section titled; "KUAL extensions", open spoiler, read text which includes the link to the KUAL/Extensions/documentation.
Computer information is stored in either a single tree (*nix, including linux on your kindle) or a tree per storage device (win*).
This forum is organized more like windows (which should not be too hard for most users, the *nix users put up with it).
The top of each information tree is always the first post of the tread dedicated to the introduction/release of the subject.
So like on Windows, when you want to find something, you start where it might be stored (say: F:\) or KUAL
Read what you find there (either under F:\ or forum\KUAL) to find the next level towards what you want.
Always read the first post, including opening any spoilers and reading the information there.
Keep a sharp eye out for any links (say to: F:\<more specific info> or Site\<first post>\<topic section>\<more specific info>
It really isn't rocket science (it is instead, computer science).
