echo "----------------------------------------------------------------------"
echo "WRAPIT works on SunOS, IRIX64, IRIX (Sgi), AIX (IBM), OSF1 (alpha),"
echo "MacOSX, HP-UX, Linux and FreeBSD operating systems. WRAPIT can handle "
echo "both f77 and f90 files. The f77 files must have a suffix of .f, .for, "
echo "or .FOR, and the f90 files a suffix of .f90, on all of the operating  "
echo "systems. All .f90 files MUST have a corresponding '"stub"' file which "
echo "contains the declarations of the f90 subroutine in fortran 77 syntax, "
echo "for example in the file '"file1.stub"' we might have the following:"
echo "C NCLFORTSTART"
echo "     subroutine DOIT (x, y, z)"
echo "     real x, y"
echo "     integer z"
echo "C NCLEND"
echo "The two comment lines C NCLFORTSTART and C NCLEND (called"
echo "delimiters) are REQUIRED. The C NCLFORTSTART appears before the"
echo "subroutine statement. The NCLEND is placed after all the declaration"
echo "statements pertaining to the arguments passed from NCL."
echo "These delimiters can be upper or lower case, or mixed case."
echo "All user fortran77 subroutines invoked from NCL must contain these "
echo "delimiters. User f77 subroutines do not require a separate 'stub'"
echo "file. User supplied f90 subroutines invoked from NCL and f90"
echo "subroutines invoked from external libraries (eg: IMSL, NAG, ..)"
echo "require such '"stub"' files."
echo " "
echo "-------------------- Command Line Options --------------------------"
echo "The six available options must appear on the command line before"
echo "the fortran file names. "
echo "OPTION: -d turns on array bounds checking, turns off optimization,"
echo "displays some debug information and prevents file cleanup." 
echo "OPTION: -h displays information comments and usage examples."
echo "OPTION: -l <libname> passes a library name to the linker."
echo "OPTION: -L <libpath> passes a directory path to the linker."
echo "  Use of the -L and -l options may require the user to specify"
echo "  more than the specific path(s) and libraries. For example, one"
echo "  might encounter the message '.so not found, etc'. In this case,"
echo "  the may have to set the environment variable LD_LIBRARY_PATH"
echo "  to assorted paths to ensure that appropriate directory paths"
echo "  are searched by the system at runtime. For example:"
echo "  setenv LD_LIBRARY_PATH /usr/local/nag/lib:/contrib/lib"
echo "OPTION: -n <so name> assigns a name to the created shared object, if"
echo "  this option is not used then the name for the created shared object"
echo "  is derived from the first fortran filename on the command line."
echo "OPTION: -q32 is used to specify a 32-bit IRIX or AIX operating"
echo "environment.  NOTE: the default is a 64-bit operating envirnonment."
echo "OPTION: -r8 is used to promote floats of real*4 to real*8."
echo "OPTION: -fPIC is used to compile with the '-fPIC' option."
echo " "
echo "------------------------ Linux Compilers ---------------------------"
echo "The default linux fortran compiler is the GNU gfortran compiler. If"
echo "your system has one of the supported linux fortran compilers you must"
echo "specify which one you want to use by the appropriate command line"
echo "option, otherwise the gfortran compiler will be used. "
echo "The supported linux fortran compilers are the Portland Group"
echo "(pgf90), the Lahey/Fujitsu (lf95), and the g95 compiler (g95),"
echo "and the Intel compiler (ifc/ifort)."
echo "OPTION: -pg  to specify the Portland Group compiler."
echo "OPTION: -lf  to specify the Lahey/Fujitsu compiler."
echo "OPTION: -in  to specify the Intel compiler."
echo "OPTION: -g95 to specify the g95 compiler."
