README 

        
Dear calc user,



See the HOWTO.INSTALL file for information on how to build and install calc.



To be sure that your version of calc is up to date, check out:



        http://www.isthe.com/chongo/tech/comp/calc/calc-download.html



We are interested in any/all feedback on recent versions of calc.

In particular we would like to hear about:



    * compiler warnings

    * compile problems

    * regression test problems (try: make check)

    * special compile flags/options that you needed

    * Makefile problems

    * help file problems

    * misc nits and typos



We would like to offer a clean compile across a wide verity of platforms,

so if you can test on several, so much the better!



If you run into problems, see the BUGS file.
