I have used both Carsten's and Eric's solution, as well as
hideshow-org (https://github.com/secelis/hideshow-org), which works
rather well and deserves a mention.

Expanding a bit on Carsten's post: Tassilo Horn wrote some convenience
functions to set the outline minor mode regexps to correspond to the
current comment syntax.  Thus, if I'm (for instance) in shell-script
mode, # * and # ** become the outline level 1 and 2 markers.

I have all this working and it's great.  But...    This is using 
outline-minor-mode.  Like Giovanni, who started this thread,  I'm used 
to orgmode, which is a little different although it uses outline mode.  
I tried hacking the code to use orgstruct-mode, which is the minor mode 
version of orgmode.  I got a little figured out, but got lost.  I would 
think all of Tassilo's code to automatically set up outline-regexp would 
still be valid, but I'm not doing something right. I saw Carsten's 
message to look at the visibility cycling and understand that, but the 
keymaps are not working right and the outline-regexp isn't being set 
right.  I've worked around the latter with a quick function I can call 
from the file buffer. However, I don't know what's going on with the 
keymap.  It looks right. For example, c-h k TAB gives this:

<tab> runs the command orgstruct-hijacker-command-102, which is an 
interactive Lisp function.
It is bound to <tab>.
(orgstruct-hijacker-command-102 ARG)
In Structure, run `org-cycle'.
Outside of structure, run the binding of `[(tab)]' or `    '.

However, it doesn't seem to recognize when it's in a structure. M-x 
org-cycle works as does M-x org-global-cycle.

I only need this for emacs-lisp-mode and verilog-mode so I simplified 
Tassilo's code like this:
(when (eq major-mode 'emacs-lisp-mode)
   (setq outline-regexp ";; [*]+ "))
(when (eq major-mode 'verilog-mode)
   (setq outline-regexp "\\s-*// [*]+ "))

Help Please!

Thanks!
