A program for using FORTRAN routines in C. The differences in calling are
hidden with a simple user interface.
This directory contains all that's necessary for using flib2c. I have tested
the program with two libraries that I needed (TWGRAPH and IMSL), a test
version for the NAG also exists (mail to the author if interested). 

FLIB2C.C:
	Main program to produce from a '.def' file the corresponding header
	file '.h'. The header file has to be included by all programs that use
	the FORTRAN library.

FLIB2C.DOC:
	The documentation for flib2c.

MAKEFILE:
	Contains rules for compiling 'flib2c', generating the header files for
	TWGRAPH and IMSL. Also compile the example programs (Works only on
	systems with installed TWGRAPH library!). They work as described
	in the TWGRAPH documentation.

The following files are only included as an illustrating example -- they can
only be used when one has access to the TWGRAPH or IMSL library!

TWGRAPH.DEF:
	Example '.def' file for the FORTRAN library TWGRAPH (available from
	the Universitaetsrechenzentrum Heidelberg). Input for 'flib2c'.
	Some additional files that are needed for a successful usage of
	TWGRAPH are omitted but can be mailed from the author.

TWGTEST1.C .. TWGTEST5.C:
	The example programs in C from the TWGRAPH documentation.

IMSL.DEF:
	Contains some declaration for the IMSL FORTRAN library. It's not
	complete because I don't have the time to scan some hundreds of pages
	of the IMSL documentation to generate the complete '.def' file.
