The author is an academcian and he used Fortran for number crunching
(there is tomography involved) because he was not comfortable with
pascal and there were code examples available from universities he
could use. So he got us to buy the Intel compiler to make the DLL:s.
Then he left after a few years and noone else understands the code.

I started out in the 60:s with Algol at university, then used
assembler in the 70:s, then pascal and C in the 80:s anmd finally
object pascal from about 1995 util now (have used all Delphi versions
until 7 and then BDS2006).
Can't get my head around the fortran code....

The dll:s are each about 16-20 files varying between 70 to 400 lines
of fortran source code.
