Not quite. (And the version string isn't in the info dictionary, too.)
If you look at that file it's something like this:
const unsigned char XYZVersionString[] __attribute__ ((used)) = "@(#)PROGRAM:XYZ PROJECT:XYZ-101" "\n";
const double XYZVersionNumber __attribute__ ((used)) = (double)101.;
where "XYZ" is your project name, and 101 your version.
So you can access those constants by including
extern const unsigned char XYZVersionString[];
extern const double XYZVersionNumber;
in the file where you want to access them, and the linker will find them for you.
