This is the FORMLINK interface which can be used for embedding FORM 
in other applications, see http://www.arxiv.org/abs/cs.SC/0604052 
Appendix D.

Installation and usage: see comments in flnk_startform.c

At the end of this file there is the demo program.  This simple demo
is an interactide algebraic "calculator" based on embedded FORM. To
compile it, one can use the following command line: 
cc -o demo_calc -DDEMO_CALC flnk_startform.c 
The executable file demo_calc must appear in the current directory.
Simply start it:
./demo_calc
and enter something like
(a+b)^100

In order to quit the program, enter CTRL-D
