Any input file name is valid. If the file name does not have
an extension, the extension .f is assumed. As KAP
processes a Fortran file, it generates four output files -
the optimized program file, the optional listing file, and the
executable file.
The default output file names are as follows:
<file>_cmp.f - the optimized Fortran program
   from the kfort driver
   <file>.cmp - the optimized Fortran program from
   kapf
   <file>.out - the annotated KAP listing file
   <file>.obj - the object file
   <file>.exe - the executable file
   
Other output file names can be specified with the /cmp
and /list qualifiers.
When KAP detects an error condition, KAP writes a message to standard error.
