Documentation to program CSS Phoebus scripts using JS and Python

[Oscar Ibañez via Tech-talk <tech-talk at aps.anl.gov>]

Hi everybody,

My name is Óscar, from Spain, and this is my first message to Tech-talk.

I am writing because I have an initiation doubt about EPICS and, more 
specifically, about Control System Studio Phoebus. In particular, I 
can't find documentation about how to program scripts using Python and 
Javascript. The different classes that are available, their special 
objets ("display", "widgets" and so on) and their methods/attributes are 
unknown for me. Inside Phoebus there are some examples, but they are not 
a formal documentation. Just a glance about some programming 
possibilities. On the Internet, in the wild, I have found some pieces of 
information, but some of them not even work when I try to use them.
However, I have read messages in this list where people use these 
concepts with no problem. So, please, where could I find documentation 
about CSS Phoebus programming?
Thank your your time.

Óscar
