Lcalc is a package for working with L-functions. The package has two
components:
1. **libLfunction**, a C++ library containing the `L_function` class.
Its class methods constitute the API of the package, and its
definition can be found in the public header `L.h`.
Correct usage of libLfunction may be gleaned from the comments in
`L.h`, from the source code to the lcalc program in `src/lcalc`, or
from the example program in `doc/examples/example.cc`.
2. **lcalc**, an executable program that uses libLfunction to perform
some common tasks.
At the moment, lcalc can compute both the zeros and values of
several families of L-functions. The default L-function that lcalc
uses is the Riemann zeta function. To compute its first ten
zeros, for example, you can run
`$ lcalc --zeros 10`
To compute its value at the point `x + yi = 0.5 + 100i`, you would
instead run
`$ lcalc --value --x=0.5 --y=100`
More examples can be found in the `lcalc(1)` man page, and a usage
summary can be obtained by running `lcalc --help`.
