Refactoring Source Navigator

[Masaoud Taher Moonim <masaoud@pspl.co.in>]

Hi,

   I went through the Source Navigator Tool and am impressed with
the functionality that it provides. I was also spending some time
studying how the Source Navigator works. However the it is a very
large tool and it is difficult for me to locate which part of the
code does what.

I am trying to build a tool which can parse a C/C++ source files,
analyze its contents and create/update the database part of it. I
would then perform my other tasks by querying the database content.

Hence I need to know the following :
1. How do I refactor the Source Navigator to only perform the backend
   part of parsing the source C/C++ files and update the database ?
   I do not need any GUI nor do I need support for Fortran, Java etc.
2. How do I invoke the C/C++ parser on the input source files ?
3. Which module updates the database with the C/C++ source info ?
4. Is there extensive API to access parts of the Database ?
5. Are there any licensing issues in this regard ?
6. Is there any other documentation available besides the one on the
   web site ?

Waiting in anticipation.

Thanks and regards,
Masaoud
