title: Doc string facility in C++
body: <p>Languages like Python, MATLAB, E-Lisp have this nice facility for  doc-strings. 
  With this feature using just a few keystrokes in the terminal,  you can fetch the documentations of the functions / module you have written and imported into your code. </p>
  
  <p>Now is there any "technique" (library, Editor tricks , whatever to )  to get a similar facility in 
  C++ / C. Suppose I include the documentation of the function within the source file at
  the head of the function, 
  then I would like to type a command like getinfo  at the terminal. (something
  like a man page)  </p>
  
  <p>I know such a 'man' facility exists for many C functions, but the documentation for these functions are written in separate text files from the source code. I would like the
  documentation to be in-place</p>
