References to larger comments...

References to larger comments...

[slists]

Hi, 

is there are something like this feature (described below) already in
emacs or some extra lisp packed 
or it has to be written.

Feature: 
In code comments there are references to a larger comments and if you
execute certain command it is expanded. 
Something like in hide-ifdef-mode for ifdefs... Large comments (texts)
would be in different file.

example:

original
/* Short comment for everyone... */ 
/* SOME REFERENCE*/

expended
/* Short comment for everyone...*/
/* Large comment, maybe on another language...  
   foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo
foo foo 
   foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo
foo foo 
   foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo
foo foo */
