This little C-program analyses the structure of FORTRAN source-code. As a 
result you get a little flow diagram in which you can recognize which 
SUBROUTINE is called by the program. Further all subroutines called from this
one are displayed. The indciation of the displayed names is a degree for the 
level.

There are several options available to check the fortran code. So you can
get a warning message for lines longer than 72 characters or SUBROUTINE calls
which are not part of the source could be displayed. 

A new addition is the change of the starting point for an analyse. Instead to
check the whole source-code you can start with a special SUBROUTINE and see
the depence of this one.

The number of files which contain the routines are not restricted by the
program. 

You can report the CALL- and/or SUBROUTINE-statements together with filenames
and line numbers to special files.

A little help-screen is printed if an input error accures or the -h option is
used. For further information see manual page.
