webcalc
=======

*through the web calculator*

Usage
-----

webcalc uses the full path of the URL as a calculator:

 ``http://127.0.0.1:5151/(5+3)/2``

Should yield a ``text/plain`` document with contents ``4.0``.

Query string arguments may be used to iterate over arguments:

 ``http://127.0.0.1:5151/(5+a)/2?a=1..10``

Values and ranges may be comma separated (e.g. ``a=1,3,5..10``).
Ranges may be specified as *start, step, end*.  If *step* is omitted,
it is taken to be 1.0.

TODO
----

 * add multiple front ends, including a graphing calculator
