Things are indeed somewhat more complex inside Eclipse.

1.- LPEX and its parsers, set of actions and commands, etc. are 
expandable.  Both the user guide & reference and the API documentation 
are available in WDSC (e.g., enter
  help
or
  help api
on any LPEX command line).

2.- LPEX ships with a few coding examples.  Enter
  ?examples
on any LPEX command line.

3.- There are two recent articles on extending LPEX.  They were written 
with another product in mind (WDz), but things should be pretty similar 
for WDSC:
