The goal of this program is to provide an open source calculator with a
simple and easy-to-use interface, similar to a command prompt, but a lot of
options and a multitude of functions.

If you need any help, you can type "help" in the command prompt, look into
the documentation - or contact me here.

There are two major versions of HC -- a CLI (command line interface) and a
GUI (graphical user interface).

There is also a (as of now, very) small FAQ here.

USAGE
=====
For much more detail, visit the official documentation.

Source code:
  - download and install the MAPM library if you don't have it already
    (URL : www.tc.umn.edu/~ringx004/mapm-main.html)
  - a simple "make" should then be enough
  - then run "./hc"
  - enter the expression of which you want to know the result, for example
    "1 + 2 * 3 / sqrt(mod(4,5))", and then press ENTER

Linux version:
  - run the "hc" binary provided in the package (either double click on it in your file
    manager, or open a terminal, then "cd" to the appropriate folder, and run "./hc")
  - enter the expression of which you want to know the result, for example
    "1 + 2 * 3 / sqrt(mod(4,5))", and then press ENTER

Windows version:
  - run the installer and follow on-screen instructions
  - enter the expression of which you want to know the result, for example
    "1 + 2 * 3 / sqrt(mod(4,5))", and then press ENTER
