[AUCTeX] help write a function?

[Leon]

Dear all,

I'd like to write a function say `LaTeX-help-at-point' that would use
latex-doc-command, latex-doc-environment and latex-doc-package to
generate help based on the context. i.e:

if it's \usepackage{XXX} call latex-doc-package; if \XXX, call
latex-doc-command; if \begin{XXX}, call latex-doc-environment.

I don't know much of lisp and I'd appreciate if anyone can help write
one. Thank you.

latex-doc-* functions are from latex-doc package.

I have attached the latex-doc.el.

latex-doc.el
Description: latex-doc.el
