fi_lib++ (2nd attempt)

30 Jan 2002

      Dear Sirs,
first of all I would like to thank you for fi_lib++.
I have just finished reading the documentation and
it turns out that fi_lib++ has almost all the features
of the library I was writing myself.  I have a few questions:
1) What is the official web site for the library?
2) Is there a mailing list for fi_lib++ users and developers?
3) If not, to whom should I report bugs and improvements?
To start with, I am having namespace problems (in my application
I need to define FILIB_NAMESPACES).  The problems I have found so
far are solved by the patch attached below.
All the best
Roberto
